We will be renting our glasses and dinnerware for reception as well as for the bar. It is being catered buffet style and will be including a champagne toast. Each table setting will have a glass champagne flute and water glass with plate and flatware.
My question is when someone goes to the bar for a beer (served by my bartender from a keg) or poured a glass of wine what is the etiquette on asking them to keep their glass to reuse if they want another round? Both our families are down to earth, no frills, but just trying to figure out how many glasses to rent, and a 60 cents a glass, it adds up! I expect about 100 guests, but probably only 50 or so drinkers. I plan to have back up plastic cups if needed. Ideas and suggestions welcomed!
