If the police were not summonded to such an event, everything turned out all right in my opinion. I cut children a lot of slack, as they are more important than my basses. If they get a hold of one of my basses, I consider that my fault. Everyone else, however, is on their own. A reprimand for having one of my basses in your hands that I did not hand you is bare minimum you'll get (Alembic Club gatherings would definitely be an exception, but still nice to ask there, too).
Interesting - I almost always bring a Steinberger with me, if playing at a venue alcohol is served at. I very seldom play it. My current one is serial number 639, I believe, and most everything just washes off it with a damp rag. I played many a biker bar in my youth. Never had a lick of trouble at those places. Trouble usually came from drunk, frustrated salarymen (and their good group of drunk friends) who were probably not going to get laid that night. Ah, the good, old daze! It ain't easy being a red-necked liberal.
