This was the first time my car ever entered a shop of any sort after getting a complete repaint. Two years without a single ding or scuff...only to have one of the grease monkeys set some of his crap down on my trunk and then move it. Presto...we've got a scuff mark on a perfect paint job. Naturally I'll never set foot in that establishment again. Unfortunately, the general work ethic and standards in my area seem to be much lower than in other places I've lived. The best service I've gotten around here was from smaller businesses where the owner actually cared about his customer. BTW, after my car was scratched, I also had to clean the driver's interior area from the same grease monkey. In the long run, it comes down to what the business owner/operator enforces in his shop.


P.S.: My other motive for not letting a shop sniff my coolant is that I want to see how this procedure works. I guess that's the curious engineer in me
Too bad you're not closer to New England, if you can push your car up here I'll be happy to let you watch, you may be disappointed though, it's really not exciting:

Open expansion tank
Start car and warm to operating temp
Attach sniffer to scan tool, set tool to sniffer mode, purge lines on sniffer etc...
put sniffer end to coolant tank opening
Let sniffer sniff
Read sniffer and check that HC is stable at 3ppm or lower
Charge customer for test
