I had a job one summer at an amusement park, and I played the part of a Wild West gunslinger in a saloon. During every show, we were supposed to be playing poker at a table while a piano player played and some saloon girls danced around. When the sheriff came through the door, we were supposed to throw our glasses and whiskey bottles at him. Of course, it was all made out of breakaway sugar glass.
The fake fight would end with the sheriff taking the bad guy into custody and justice triumphed over evil once again. For us actors, we would wait until the audience left, then sweep all the glass off the floor and start over with fresh sugar glass bottles. I'm glad I wasn't the person who had to buy those sugar glass bottles, because we did 5 shows a day, 7 days a week.
