For all of those still stuck on doing a cash bar... Go to a party or a wedding as a guest with a cash bar and see how you feel. Just went to my cousins sweet 16 last night and my notoriously cheap aunt had a cash bar. It shouldn't have been a shock, but it was. Having to walk back to my purse to get a card to put on file because I had no cash was uncomfortable and annoying. Sorry.. Just still aggravated about it today.
