Hi.
Zero, most of the time.
I'm not kidding either.
We were hired to do a gig. An amplified acoustic gig. Quite far away.
I told numerous times that we weren't exactly a folk dance kind of a band, but the guy insisted. We played mostly CCR, Neil Young, that sort of thing and he knew that.
When we arrived, the sign said: "THE APEMEN" ; WE'RE DANCING TONIGHT.
We knew immediately that we were in trouble.
We played three sets to an empty tent (they insisted that we stayed in there). Exept for one song

.
Granted, people were there outside of the tent eating barbecued pig and boozing, applauding at the end of each song, but save the dog (really) and an occasional curious kid, we were left virtually alone. The only song that got the people dancing was the "Sultans Of Swing" by Dire Straits. We played that one quite a few times

.
We got paid what was agreed beforehand, and the people seemed to be quite happy, but it was extremely hard to play when no-one was listening. A paid rehearsal would be a fitting description.
Regards
Sam
