I used to have a BF who had a very nice family & I was invited for a few family dinners at his parents' house over the course of our relationship. Each time, I had a glass of milk set down in front of me. I don't like milk, and have never been given only milk as beverage choice since I was in grade school. Would it have been rude to ask for a glass of water? (I never did b/c it was already poured). I mean, I don't expect a restaurant menu of drink choices, but I'd seriously prefer water or nothing to drinking milk. And in this instance, is it rude not to drink what's put in front of you?
