Enough is enough: 'Take away their kids'!

Last Friday I went to pick up a pizza. I called in my order ahead of time so I'm only picking up. My oldest son who is 4 wants to come along(all my kids love to go outside). I believe it was warm upper 20's. So I have all 4 windows open and the sunroof open when I park the car. I tell my boy to just wait in the car since I'm parked in front of store and will only be a minute. I get inside the store and these freekin clowns screw up my order and will have to make another pie. I tell them ok I'm getting my boy he's not waiting in the car by himself. I bring in my boy and he's very exited to be in the pizza shop. I start getting real pissed off at the staff for screwing up a simple order and since I'm a regular customer for 10+ years they give me 2 additional pies and extra dipping sauces free of charge. I tell the staff I can't stay angry at them because they treat me good. Best part is my son gets a good lesson in life from just being with me.
Ya that woman deserved to get scolded at! And I have myself yelled at people who had it coming.

Might I suggest another remedy?  Particularly since "taking away" a dead child isn't much of a deterrent?

If kids are found in a sweltering car while parent is in the mall trying on hats, what if we took away their CAR?  No need to break up a family just to keep those kids from being locked in a hotbox.
