I have a friend who finds it uncomfortable when I cater for him as he's not used to the effort and doesn't like me being put out, but I do it anyway as I have to cater for others so for me its really not all that difficult.

It would annoy me if someone were that rude, I would possibly tell her to cater for herself if she were that ungrateful.

I like to serve people food that they would typically choose to eat rather than just eating what's in front of me because its there, so I do tend to go to more effort. But as I said it doesn't really bother me.
