Unfortunately, my boss was a horrible snowflake recently.
Boss and I went to a conference recently - the sort where you book and pay to attend, and in return they give you lots of yummy food along with the conference content.
Conference comes, and then food is laid out for lunch. Along with the hot foods and salad, there's a sealed Caesar salad sitting off to the side. Boss is on a diet, and so opens up the Caesar salad because it has more lettuce and he isn't going to eat anything else.
Me: That's a sealed salad, and there's a name on the side. That's for someone specific.
Boss: Why would they get their own salad?
Me: They probably can't eat anything else because of food allergies. Leave it and eat the other salad.
Boss: Its fine. They're not here, so they don't want it, and besides there's plenty. And if they want more salad, they can eat the shared one as well.
Me: No, the open salad might contain what their allergic too, or be cross-contaminated from the kitchen.
And then continued to dole out forkfuls of the sealed salad onto his plate.
To whoever it was that went hungry that day, I'm so sorry.
