Quannah Parker Walmart Self-Checkout Only Project Update I had the opportunity to skip out of work a little early yesterday, and it was such a nice day I decided that tossing something on the grill was in store for dinner. While I'm a trite and true charcoal man personally, I get tired of messing around with the coals, especially if I'm not cooking a ton of food. It's a big charcoal grill, so I decided I'd hot swap an empty propane tank over at Walmart since I had an abundance of spare time I'd normally be using to watch YouTube while putting in my time.
