When I was a waiter in a fairly upscale restaurant twenty years ago this one family who were regular customers would always ceremoniously order a round of beers after a really big dinner. It's not like they were big beer drinkers as they always ordered cocktails before dinner and fine wine with dinner. For some reason, at the time, I never thought to ask them what the origination of this practice was. Has anyone else ever seen or done this? Is it a tradition or custom somewhere?
