my wife and I have a little joke about this; it goes like this..... "ah? who had the coke?"
long story, but I've been paying tabs all my life. Whatyagonnado?
It does piss a guy off when this stuff happens, but I'm thankful that I've always had the resources to just pay the (entire) tab and forget about it. Last one was around $500. If money is tight, I'd think option #4 would be the option.
Sorry to hear about your great friendships
