Hi, I have read so much about cash bars, that I am a little confused. We are hosting beer and wine all night, so that is not the issue. Soda, tea, and juice are also available, of course. Is it rude to also let people have the ability to purchase their own mixed drink/hard liquor if that is what they want to do? I know not everyone likes beer and wine, and I just want them to have a choice. Is this acceptable?
