This is why we (pinsiders) the guys who bring the machines have to insist that when tickets or bands are being sold at the counter a friendly reminder is given to please have respect for the machines as they are someone else's property. Maybe even a few signs here or there.
Again I do not drink alcohol and think that it fuels stupid actions at events because too much is served. I see too many attendees leave at night that would blow over .08 guaranteed, wait for the first time that comes back on a show! =no more shows
