My future inlaws are planning our rehearsal dinner, or rather, cocktail hour. Our rehearsal is at 3pm the day before and they are planning to have a cocktail hour with drinks, pizza cut up into little strips, and crab dip. The only thing is that they are planning to have a cash bar. That's a no-no, right? I've already agreed to let them host the rehearsal dinner, but now I'm regretting it.
