So I just attended a wedding where the "open bar" only lasted one hour--well 42 minutes to be exact. Afterwards beer, wine and soda were no charge but we had to shell out $7-$9 per drink at the bar. Not expecting this I didn't bring a lot of extra money with me as I was told earlier that the "open bar" would last longer. My question is: would it be considered tacky to put placecards on each table so guests could read how long the "open bar" will last and how much approx. drinks would cost afterwards? I heard several party guests complaining aboth the high costs of the drinks at the bar after they found out the "open bar" was closed. I would rather my guests know kind of what to expect than to be shocked when they went to the bar for a drink for them and their date and only get back $1-$2 change from a twenty dollar bill. The investment in the wedding is expensive enough and then to have to add another unexpected $40-$60+ per couple to the night for additional mixed drinks left a sour note with some guests. I certainly don't want that reaction at my reception.
