Paddy,

I would check with you local Musicians Union (if you are a member), if not I think they will still answer your question.

My son worked in Bars as a waiter/bus boy, the stipulation was that he was not allowed to serve alcoholic beverages, only food and soft drinks.

Willie-O, I remember those days as well, also that one glass had to be empty before they would serve or sling you another one.
