What a Supermarket Taught Me About Being an Introvert

My first proper job was in a supermarket. Weekends in the bakery, then eventually the checkouts.

I was sixteen. I had no idea I was an introvert, or even what an introvert was.

I just knew that by the time I got home in the evening I was completely done in a way I couldn’t really explain.

Not physically tired, though I was that too. Something else. A kind of flatness that needed the sofa, the quiet, and absolutely nobody talking to me for at least two hours before I felt like myself again.

I assumed everyone felt that way after a shift. It took me an embarrassingly long time to realise they didn’t.

Some of my colleagues loved it. The busy Saturday rush, the banter with customers, the chaos of the bakery when it got hectic. They were energised by it. I was depleted by the same things. We were doing identical jobs and having completely different experiences of them, and I never really understood why.

That was my first lesson, even though I wouldn’t have been able to name it at the time. The problem was never the environment. It was that I was measuring myself against people who were wired differently and wondering why I kept coming up short.

The checkouts were interesting in a different way. The bakery at least had gaps, moments where you could focus on the work without someone in front of you or hide in back for five minutes.

The checkouts were relentless. Customer after customer, small talk expected, smile required, no natural pause in the interaction until your break came around. I could do it. I wasn’t unfriendly or awkward. But every conversation cost something, and there were a lot of conversations in an eight hour Saturday shift.

What I learned to do, without really thinking of it as a strategy, was find the small pockets of quiet within the noise. A few minutes in the stock room. The walk to the break room. Even just the thirty seconds between one customer leaving and the next arriving.

Volunteering to go outside and collect trolleys was my favourite.

I was unconsciously protecting myself in tiny increments because the alternative was running completely empty before lunchtime.

I also noticed that the interactions I found least draining were the ones where I was actually useful. Someone looking for something specific, a question I could answer properly, a customer who wanted to know which loaf was best for sandwiches rather than just picking one at random. Genuine connection, even brief, felt different to obligatory performance. That distinction has stayed with me for thirty years.

It also quietly dismantled something I’d believed about myself for years. I’d always thought I was shy. Shy was the word people used for me at school, the word I’d use if anyone asked. Quiet. Shy. A bit awkward.

But shy and introverted aren’t the same thing, and the checkouts helped me figure that out without ever using either word. Shy is fear of social interaction. What I had was something different. I could talk to people all day. I could be warm, helpful, even funny with customers. I just needed to recover from it afterwards. That’s not shyness. That’s introversion. The distinction sounds small but it changes how you see yourself entirely. I wasn’t someone who struggled to connect with people. I was someone who found it costly in a way that extroverts simply don’t.

The other thing the supermarket taught me, and this one took longer to understand, was that doing a people-facing job well doesn’t mean it suits you naturally. I was good at the checkout. Customers didn’t leave thinking they’d been served by someone who’d rather be somewhere else. But competence and comfort are not the same thing, and confusing the two is something a lot of introverts do for most of their careers.

Being able to perform in an extroverted environment is a skill. It is genuinely useful and worth developing. But it is not evidence that you don’t need to recover from it. And the recovery isn’t weakness. It’s just the other side of the equation that nobody talks about.

I went on from that supermarket job to spend twenty years in recruitment, which if anything is an even more extroverted environment than a Saturday checkout. A lot of the same lessons applied, just at higher stakes and with more complex consequences. But the foundations were all there in the bakery on a busy Saturday morning, if I’d known what I was looking at.

The version of me that was sixteen and dragging himself home on the bus at seven o’clock, staring out the window needing silence, wasn’t struggling. He was just an introvert in an extroverted job, doing what introverts in extroverted jobs have always done.

Getting through it. And quietly figuring out how.
