I have operated many different registrations both on AOC and "private". When operating "private", and I use that term as opposed to CAT, and the owner or the company is on business, they rarely find the need to explain to me what their business is that day, I guess they think its none of my business.
Maybe long finals has a similar situation. If we can get cheaper fuel why not, things are tough enough and if we can help the boss a little it helps to keep us off the job market and sniffing around other operators for jobs, that would help to bring the pay scales down and then we all lose.
