I tip exclusively with $2 bills because bartenders/event staff/doormen/shuttle people then always remember me. I get them from the bank and they are invariably crisp and never been folded. They kind of stick together because of this, too.
Same! Nothing speaks louder than having a wallet that's barely able to fold because it's full of $2 bills, and being 'that person' who pays exclusively with them. It immediately gives you a unique flair.
Also, I've noticed that requesting $2 bills is an interesting test of your bank's ability to perform its job as a member bank of the Federal Reserve. I've had so many tellers tell me that $2 bills no longer exist, only to have their managers offer to call me when they arrive in about a week's time.
interesting. I do this in Seattle all the time. Nothing like this seems to be assumed. I must tip in places that either hide their reaction well or do not assume that ;-\
