I actually deliver out of the back door more often just to let some hot air out. The outside temp is bearable, the inside temp is the killer. Knowing if you leave your door open one nano second while delivering could ease the heat, but you will be caught, puts us in severe jeopardy. Cool the inside down to like 100 or lose your livelihood for trying. We dont need air, at least in Ohio, we just need management to say, yeah, open the door for a short time and air it out a bit. But no that nasty TSA is out there waiting, give me a break. Especially when there are heat warning, and they do nothing to lessen the work day. Silliness. Be human.
