I slackened off a few months back for more money.
Missed frosted windows, did less rinsing, didn't do frames on most, didn't detail trad stuff...etc...
Made noticably more money, but got tired, as I found it also encouraged me to spend all day rushing about flat out, to see how much I could do.
Got a complaint too, and that was the end of that.

Might do it today though, as I've got an area that I wouldn't finish and have to go back up on monday otherwise...
