Agreed with officertyo!!! I run a shop and we are not here for free service people. We get paid off of commission, service adviser gets paid off of commission and technicians get paid off of commission. The whole shop gets paid off of commission. I dont blame the guy, he probably charged you .2 hours which is the bare minimum any shop will charge you for labor of any sort. To be honest if someone would complain for a $16 bill I would probably trespass that person. You have a BMW guy maintenance is going to be expensive, everything will be expensive on these cars. If your complaing about a bill for $16 sell it and get something else
