Thanks Jen,
   The door charge was a free will donation collected by the performing family and all of it went the hospital. The family were not paid to perform although some made their living from music. It was an arrangement between the owner and this family that was to benefit the hospital. Of course the owner did very well on bar sales that would normally be low on a Saturday afternoon and the family had a venue to get together and jam among themselves and with friends.
I suspect that the owner may have believed that the clear liquid in the water bottle may not have been pure h2o, but I don't really know the truth of that. In any case the goose that laid the golden eggs became the meal.
