The venue my reception is in has a traditional, fully stocked bar. They are requiring us to pay based on consumption (and will not do flat fee/guest) and so we're doing beer, wine, and 2 signature drinks.
1. Dilemma #1--what to do about the "other" drinks the bar serves? It's not like the bar will hide its bottles of scotch, so how do I avoid my guests inadvertently paying for their own drinks? Is it better etiquette to allow the bar to serve them at a cash price, or to tell guests they're not available?
2. Dilemma #2--with the consumption pricing, my (paying) parents want to set a limit at which point the bar switches to cash (I know this is against etiquette). Problem is, my friends are heavy drinkers, and my parents started their estimates by assuming 4 drinks/guest over the 6 hours. I'm almost positive my friends will drink more than that, though perhaps the more "adult" guests will offset it. Any advice in handling consumption pricing?
