Is there a list of acceptable office foodstuffs someone might like to share?
Anything that doesn't stink. Although I guess it does depend on the office. Our communal kitchen is completely open plan and right next to people's desks (mine!). Smelly food is distracting and irritating. Non-smelly food isn't.
For the avoidance of doubt, I have no problem with garlic, bacon, fish pie, curry etc when relaxing in a restaurant with friends. It's just when I'm up to my eyes in spreadsheets and trying to stay sane that the pungent mixture of all the above wafting around my desk makes me a little edgy.
