I'm curious now. What do companies that give out company shirts or jackets do when everyone is male so there is no male/female style problem, but some of the males are fat enough or tall enough to need a big & tall size, and those sizes are not available or are a special order for the shirt/jacket they've chosen?

There is enough basis in fact for the fat programmer stereotype that this surely must come up now and then.

Another one I've seen is giving out food. My employer gave out hams one Christmas. There was one vegetarian, but he was a vegetarian for health reasons, not moral reasons, and was OK with getting that gift and then giving it to a friend of his who liked ham and everyone was happy.

But what if we'd had someone who was vegetarian for religious reasons? Or someone who was not vegetarian but could not eat ham for religious reasons? Could giving out that ham be construed as discriminating against them on religious grounds? And would it matter that it was given out for Christmas, which is nominally a religious holiday, as opposed to if it had been given out for, say, President's Day, which is completely non-religious?
