gr8golf88,
i agree with your point. if we need to supervise closely, something is not right. anyway, i do most people do that when my car is service i stay around to see see look look (to learn something) and also to be present so that the worker do a better job? ......
my tyres have been taken down/up for at least 10 times (change tyres, rims, adjust coilover, service brakes, etc)
i have never seen a single case that the worker handle the rim super careful. they squat, put the gun in fast and forcibly and start tak tak tak tak ....
i guess no worker will treat rim like owner do ... can we expect that level of careful and attention ?
