Mr 123.....I have a musician friend that used to do a song in his set...."Party til the money runs out"....goes like this in the bridge.......

"Party til the money runs out, Party til the money runs out....If you wanna know who the real friends are just party til the money runs out" the message is watch the place clear out once you close your bar tab........Your real friends stick aroud and make sure you get home ok....
