An older couple came into the restaurant looking for a table. The hostess, who is ~ 16, proceeds to tell them it will be 15 minutes until the table is ready.
Two minutes later, the man comes back and asks again for the table. The hostess again says 15 minutes.
At this point he pokes her in the forehead and tells her, "I don't need to be told that by a 12 year old."
Good thing I wasn't there, he would have been arrested.
