Richard, don't worry it's all hypothetical and I don't think you're an asshole and hope you don't think I am one either. I grew up with three brothers and if you didn't fight and argue you didn't get anything. So this stuff is more fun than it is serious.
Would I maroon one guy there for four hours, no I wouldn't do that unless we were so busy we didn't have a choice. We are fortunate to have extra equipment and we have the technicians, so no I would still send two guys to knock it out.
As far as them being thrilled about working for an hour, probably no, we would want to line up other work so they could maximize their time. Again if they wanted to cut out of here early the following day or make a short Friday, they could.
We tell all technicans when we hire them we work when there is work, it' not always 8-4:30 and if they have a problem with hours they probaly won't work out here.
We do like to process the work quickly, being in the emergency business, you truly never know what the next hour will bring and I'd rather have the job done and out of the way that be strapped as to what to do now that I have this job and a water loss, or two.
I'm not suggesting it for everyone, hell I wouldn't even do it unless everything worked out to where you could actually process the job at that those numbers. I'd also want to be secure about a payment and in reasonable time.
