Hello all -- first post here. I am a bride to be living in Milwaukee, Wisconsin and marrying in my homestate of Iowa in June of 2014. I am sure this question has been asked before but all of the posts I have found on tipping have been related to tipping vendors. My question is whether it is acceptable to have a tip jar for drink servers that our guests pay into when they are served a hosted drink. I have read enough posts around here to know that many posters feel that it is never acceptable to ask guests to open their wallets, but I am curious if this is true even to tip for drinks that one receives for free.
My venue is an old barn and I plan on paying college students who are fundraising for an international service trip to serve keg beer and wine to our guests. I work in international education and so for me this is perfect, but I had only anticipated paying them minimum wage and then allowing them to keep all of the tips they made. I know I have tipped at other hosted bars and not thought anything of it, but I am curious what all of you have to say.
Thanks for your input!
