I was going to grill up some Salmon last night. Go to make a packet in tin foil. No foil. Renter used it all and apparently I'm supposed to know and refill I guess. Oh well, I'll just cook it right on the grate. Go to light the grill, no propane! He cooked like 20lbs of ribs last week and apparently used all the propane. Never re-filled the tank or even bothered to let me know. WTF?!
