I once ate a can of sardines on my lunch break. I was parked in a dirt lot behind a Circle K in Casa Grande, AZ. It was over 110F that day.
On my way to the inside of the store to get a cup of coffee, I tossed the empty sardine can into the dumpster behind the store. On my way back, I had to take a wide berth around the trach can, because the fish stench had become overwhelming in the heat, in just those few minutes.
It doesn’t take long. At home I usually rinse the can out and still put it in the outside trash can right away.
