When I was in high school i worked in a restaurant, the Holiday Inn. In the summer my boss would special order Sarsaparilla (root beer), he was have the waitress push selling that to the customers. We would also put a few six packs in the walk in freezer till it got super ice cold and when our boss would leave in the evening we would drink it and make root beer floats. It would sell for around $2.00 a bottle back then (late 80s). If he only knew he would be pissed off, because we would drink more root beer than they sold.
