Not on a $57 check. I'd say the waitperson was expecting the appropriate tip. Giving me back two twenties and three singles is just begging for trouble, in my opinion. Assuming that the $57 did not include taxes and that the service was good, I would have been prepared to tip around $11, so the change received by the OP would have been useless to me, again, assuming that I didn't have other denominations (besides $100s) in my pocket. I wouldn't want the waitperson to assume that. Bring me the change that will make it easiest to give you the "right" tip. Even if I was planning to tip 10% or 15% for crappy service, I'd still need something besides two $20s and three $1s.
