Who: The guy who fills up his cup at the convenience store soda fountain, drinks half of it and refills it before paying.
Why: He takes the cup and loads it with his soft drink of choice. Then, there’s this slight shifty-eyed glance around to see if he’s being watched and –bang – he downs a large portion of the pop and places the cup back under the spout to fill it once more. That’s when he makes his way to the register to pay.
How I justify it: He acts like he’s tasting it to see if the convenience store dispensed liquid meets his delicate sensibilities and satisfies his gourmand-like taste buds but we all know THE SUMBITCH IS STEALING!
