That urge to buy

Could it be that working on a large university campus condemns me to all sorts of weird encounters? Or have you find yourself in the same predicament?

I visited the restroom down the hall today just to hear some guy talking on his cell from one of the stalls. Expected restroom noises provided the background for his telephone purchase, and he gave out credit card number, expiration date and security code. Let us leave aside for a second the misplaced trust in your fellow restroom user (maybe he was thinking, they might not be able to use a pen or a voice recorder?). Let us ignore also common respect for the person on the other end of the line. My real question is, what would you really need to buy right then and there? Massive quantities of Preparation H? Adult diapers?

Or maybe the association is looser: an ejectable seat for your Aston Martin? A new armchair for the living room? The sequel to the book you just finished during your current endeavor?
