Many years ago a friend of mine used to tip bartenders and servers with dollar coins (a dollar tip on a drink was good at the time). They remembered him for that and he got better service even though it was probably a bit of a PITA for them to deal with the coins. $2 bills could probaby be used in a similar fashion.

Tips are a good use because they go into the pocket, not the cash register - and it makes you memorable.

> they go into the pocket

That is, assuming the worker has a pocket to receive the tips.
