What is the proper etiquette for bachelor and bachelorette parties in terms of cost to the guests? I know this is one type of event that is not typically on the couples' dime, and that makes me generally uncomfortable.
Every bachelorette party I have attended has involved some awkward situation regarding money over limos, shows, bar/club preferences, or the 2-hour fight over fairly splitting the bill fifteen ways at the restaurant when the waiter inevitably confuses the tabs. In the past, when there has been a situation where one guest could not afford their share of the limo or the dinner bill is not adding up, I am always the one to pitch in and cover the conflict. I don't want it to ruin the party and the bride's evening, but I also feel a little annoyed that these problems come up time and time again and I definitely don't want any of my girls to fall into that predicament. My fiance says that he encounters the same thing at all of the bachelor parties he has attended, but we both agree that under no circumstances would our guests allow us to pay for the events, or even pay for ourselves.
How does a bride or groom handle throwing a party that will be the fun, outrageous, and inescapably costly (NYC$$$$) event that some of the guests want, expect and gladly afford...while still respecting the attendees that don't have the disposable income but want to be there for the celebration (and avoid judgement/scorn)?
