Meanwhile, I'll be in a restaurant waiting for the place to cool because I changed an AC compressor earlier in the day. While I'm in there, I'm also changing a Delfield thermostat that rusted closed. While I'm waiting for THAT to cycle, I'm replacing a gas valve in a Pitco fryer I condemned last week. As I'm walking out the door, the manager will ask me to look at a light fixture in the kitchen that just went out - it will need a ballast - so I'll return tomorrow with the ballast. Ten hour day and more work for tomorrow.
The more you know, the more you work. The more you work, the more you make.
