I received an invitation to a party that included a request to bring a certain dish for the dinner. I have heard from other invitees that they received similar requests.
Queenie, is this some new custom or am I right to feel imposed on?—Guesti-Ket
Such an invitation is totally inappropriate. A situation like this makes you more of a co-host than a guest. Feel free to decline the invitation, or to accept on the condition that you will not be responsible for helping to feed the other guests.
