When I was a kid, my dad had one of the round, open, BBQ grills. You remember the type, it had a single peg in the middle of the grill and could be adjusted for height. The only real drawback to this type grill was that once you built the fire, you couldn't save the charcoalwhen you were done cooking. There was no way to cut the air-flow to snuff out the coals.
Our neighbor was so tight, when he saw my dad cooking on the grill he woould walk over about the time dad would be finishing up. Carroll was a tall, gangly country fellow and would say, " Ed, I noticed that you're about done cooking. Would it be alright if I "borried" (borrowed) your grill? Those coals are going to burn to ash anyway, no sense in letting them go to waste?"
I don't think old Carroll ever bought any charcoal or a grill until they came out with the grills with the lids.
