Well, I can't profess to actually spending it all on boozery, but all I can remember buying before I blacked out was booze. And I did wake up with two bottles of whiskey in my bed. Plus the $90some receipt I found in my pants the next day. My bank statement showed a withdrawal of $200 and all I had left was a $20.
That was Friday. Something similar to this happens pretty much every weekend. Not usually so much money though. Often I get away with only spending $40 or so myself and conning people into giving me alcohol.
