My FI wants an open bar. He drinks beer as well as most of his friends and most of the rest of his family drinks wine so I figured that a beer and wine bar would work.....except I drink niether. We are providing the alcohol and figured it's open bar till it's gone. My friends are heavy drinkers and love liquor but drink beer as well if it is all that is offered. I drink one particular mixed drink only. Would it be rude to have the bar tender keeps ingredients for my mixed drink and only make it for me or should I provide the option for others to have it as well? I'm just worried that if I give the option by the end of the night there will be none left for myself.
