Sometimes that big green check mark just isn't enough! I can't agree with Jolene more, sometimes when I'm in a model's room and the countdown is more than 2k, getting guys to chuck some tokens at it can be a Herculean task. If I typically buy song requests or other such things, and the model allows it, I'll buy a big chunk of them just to knock down that wall some, after that, I've typically seen rooms much more willing to throw tokens at a progressing countdown.
Woops, noticed what section I'm in, IANAM (I am not a model)
