I see a lot of people referencing this. I am NOT saying that this is what my fiance and I are doing, but I am just wondering why is it rude to have a cash bar? I think it is rude to expect the bride/groom to pay for everyone's drinks all night. Or is it just rude to have a cash only bar? So if they had kegs and wine for everyone to drink for free and all cocktails were cash bar style then it is fine?
