Cheat codes for drunken masters

Answer 1

There are only two for the free online version, EASYMONEY and UNBREAKABLE:

EASYMONEY gives you a small amount of startup cash, and

UNBREAKABLE makes everything, well, unbreakable. Which is really useful when you perform a lot of flares and you accidentally drop a bottle or a glass.

(Note from developer: Unbreakable has been known to cause problems with the game - including glasses falling through the bar and rendering the game and save file unplayable. I'd stick to easymoney.)
