To clarify - Administrative & Professional staff were VP's, Department Heads, Managers, Directors etc.
Administrative Professionals is a term applied to clerical staff like secretaries, clerks, assistants and other support staff.
Huge difference but meant to illustrate what other posters had said about the top dogs thinking they were entitled to everything.
So the reception was for people in Group A, but somehow Boss got it in her head that it was for people in her
group, Group B? The names are quite similar, yes, but you would think those in the industry would know the difference, and that the flyer would additionally say something like, "A reception to honor our hard-working clerical and support staff." I don't know, it might have been interesting going with her, just to see if she made a fool of herself. On the other hand, if it was a large enough event, she might have been able to fill a plate with free food (that wasn't for her) without anyone really noticing, and thus wouldn't suffer any consequences. Don't you think she wondered why none of her colleagues were there, though? And why the place was filled with secretaries? So strange!
Re: the chicken salad sandwiches. I get being angry about the money and effort going to waste--to me it seems a bit odd that the school would ask parents to bring in food for the teachers in the first place. IME with public US schools, teachers do get a fair amount of food/treats at the holidays, but as a totally voluntary thing from the students/their parents--I've not heard of a school specifically putting out a request to feed the teachers. Anyway, if this request had resulted in so much food that the teachers couldn't eat it all that day, yeah, someone should have been in charge of dividing stuff and packing it up safely for later--I'm sure there were a number of other things that went bad, if they sat out all day, and that's just a waste all around.
Honestly I would have been tempted to just leave it there--let someone else realize the problem and throw it out, but at least now I know what's really going on--but I probably would have been concerned that some unsuspecting person would get sick. I think throwing it out at the school would have been fine, if you could have played it like, "What?! These sat out all day?! Oh no, they're ruined now, no one should eat them! We need to dispose of them right away before anyone tries to eat one!" Then dump the plate in their trash, let them deal with the disposal. Doubt I would have given them anymore food in the future, or at least not spent much time/money on it--to me it's not about, I'm insulted that people didn't like my food, it's more like, Wow, they totally and completely wasted that resource I donated to them, that shows a real lack of appreciation and organizational ability. Not sure I want to invest much more in that again.
