Yeah, this is why I stopped. Participating in all office food days. The hassle is not worth the effort. I don't bring anything, and I don't eat anything that was shared. I pack my own and stick to myself on food days. Whenever asked I just say I'm on a strict diatary requirement from my doc and leave it at that. I'm not trying to make friends or 'be a part of the work family'. Did that for 16yrs, all it got me was laid off.
