You're walking home from work when it begins raining. Hard. You check your bag for your umbrella, but you left it at home. You sigh as you see the dark rain clouds over head, and run into the nearest shop for cover until the storm blows over.

As you walk around, you realize you've run into a bar. You sit on a barstool and wait for the bartender to pour you a drink. Someone calls to the bartender as they sit on the barstool next to you, saying: "Hey! Put whatever they're having on my tab!"
