My band generally has a tip jar out front, conspicuosly placed, and is often full after the nights session. Often it's NOT !!

However, for most functions, public or private we check first with the patron regardless. No assumptions made.

Upscale is usually more generous than the local bar, but hey... if it's not there, customers often do not know what to do with that couple of bucks.....and will often walk up mid song which is distracting to most of the band... especially if the crowd has been drinking... we want to make sure they don't fall over monitors, spill drinks, trip over cables or mics stands... LOL !!

Bottom line.. clear it with the manangement first !!
