I worked for a commercial dive company for a while, and we ended up landing a government contract to install a plug in a pool on a military base so that another contracted company could change the pump. Because it was a gov. contract, the gov. dictated our wages. The state wage for commercial diver was $84 an hour and that is what the contract mandated our company to pay us. So after set up, drive, set up, dive, break down, drive, break down we got 6 hours at $84 twice. One for a 5 minute wooden plug install and One for the removal the next day.

edit: There were definitely post work beers those days.
