Post office

never heard of the USPS running out of stamps, but i know of El Pollo Loco out of chicken, and Del Taco out of taco shells... and Starbucks out of a certain kind of coffee.. lol.
 
Lots of good additions to this....I'm just SO surprised that any store/service would run out of their key item, and remain open. And I just wanted regular stamps...any stamps.
