Am I the only one that considers lunch to be a sacred, personal time that I don't want to spend on small talk with coworkers? I need my lunch break to recover from the day's stress and pace, so I can come back refreshed and ready to code for 4-5 more hours. As an introvert, I find the team lunches to be waay more stressful than actual work, and that eliminates any benefits of a nicely cooked meal. If I end up in a team lunch situation, I find it hard to be productive for the rest of the day (unless I take a separate mini-lunch break by myself later).
The situation was especially bad at one recent job where the lunch conversations always revolved around local sports, which I had no interest in, or this guy remodeling his house, which was only interesting the first 3 times he gave us an update. So I started bringing sandwiches to work, parking in the garage beneath the building, and eating lunch all alone in my car in the dark, listening to NPR or just enjoying the silence. It was the most refreshing hour of my workday and I felt 200% more productive after that break than I would after 30 minutes of small talk about sports.
I just want to point this out to people who think team lunches should be mandatory. Not everyone enjoys them equally, and it's not always just about the food.
