Since I went on my own and it's just me I don't do supermarkets. Kind of miss working on racks and protocols but no way a one man shop can take that on. My wife stays home as well and runs the kids around and all the other stuff she does.Supermarket Refrigeration here, but I'm not the owner. I do love the work most of the time, and it has allowed me to afford a nice life and a wife who was able to raise our children rather than having to manage competing schedules.
It is an extremely demanding field and being one of the "go to" guys even more so.
In the past few years, I've reached a point where I can take a week to hunt but for many years, I got a few Saturday Mornings and maybe the opener.
