This same issue comes up and I DO NOT GET IT.

In my last workplace the co workers I worked with seemed obsessed with two things (1) Planning Parties and (2) having food that, frankly, no one likes. One good thing is that my new boss has sort of temporary workers so... this really varies.

But now, these two temps have decided on making their own food in the workplace and have suggested that every week we have a group lunch with them making food.

(1) I usually get invited to this as a food consumption participate. They make too much food and need someone to eat it.
(2) They are, of course... thin, and I am fat. So, that is annoying.
(3) The food is horrible. I have stated a few times that I am not a Mexican food person... and they always make that and go out to eat there.

One issue is that they always act like i am a kill joy that I don't want to do this. Obviously because they want me to consume their food so they don't have to clean up.

I try, so hard, to make it clear that I don't want to do this.. for many reasons, including that my job is such that I can't really be away from my desk for hours. I also resent that they have work to do and I hate that when hours go by and I am waiting for something they tell me they went shopping for food.

But they don't get it. And I feel they don't because they feel i should just eat to help them out.

I would just come out and say it but, I don't know if I can because that would be kind of rude. I just wish they would get the hint.

This happened now in two different workplaces -- what is the deal?
