We are having an open bar and bringing our own beer, wine, liquor in. A bartender is being provided by the venue for a $150 fee. I plan on tipping him what the venue says at $100. Is it okay for me to allow him to put out a jar/base for tips at the bar? I am not sure about the etiquette of this...
Add on: They are also paid with gratuity from our venue, ceremony, corkage, surcharges (20%), and catering fees. I just asked the venue if we needed to tip beyond that and they said $75-100 was what some brides choose to tip at the end of the evening. I chose to be the bride that adds on to the fees & gratuity already paid. I was just not sure about the tip jar since I had seen it at other weddings.
