Just took van in to auto electrician /mechanics shop.
Mechanic wasn't there, but auto electrics guy was.
He helped me out before cheap ($20 to come out to my vehicle, sus out why it wouldn't start, got it started, did some checks/tests once back at shop).
Today he was nice enough to say "it's not hard to do yourself" then proceeded to explain, in detail, step by step, exactly how to change air con belt. Explained my air con isn't stock, so finding correct belt will be difficult. Also checked to see if there was gas in air con, all without charge .
There was something that bothered me though. He had flipped up seat in van to reveal engine bay (and air con belt)
Hovering over engine bay with a lit cigarette
Now firstly, I'm wondering How dangerous is this? or is it reasonably safe perhaps, and this is acceptable?
For those that do mechanical work at home, or have mates that do their own car work, would you or mates have lit cigarette while your working, and think nothing of it ?
Secondly; How would you say it to him, tell him not to do it, without having him take offense and likely ruining a good relationship there?
Like with how nice he has been, I don't want to be rude. Also I don't know if it's safe or not, he's obviously been doing this a long time, who am I to tell a tradie how to do his job.
I did step back abit when he was showing me how to change air con belt myself, when I spotted the lit cigarette right there hovering over everything.
He's probably been doing it his whole life without issue. There's only one likely outcome from your suggestion, and it probably involves a black eye. (Yours).
Don't bother. Take your car elsewhere if it bothers you that much.
