A truly unscrupulous mechanic shop would fold fast. Sure, I'm sure a lot of people's grandmother's hae been charged for refiling the blinker fluid, but more often than not people are accusing an honest person.
I don't know about other people, but if a customer started reaally grilling me, asking for pressure readings, I'd show them the door. I would take it personally when somebody who knows little about cars and thus has no evidence starts accusing me of trying to steal.
I'd get a second opinion and take it from there. Don't go randomly accusing, but don't be a sucker.
Most shops are honest.
The only way I could answer a question such as how do I know if an AC compressor needs to be replaced is to look @ the head and suction pressures or understand what failed. I can't give a good opinion without knowing some facts.
If asked in the respectful way such "Please help me better understand the reason I need to buy a new compressor...", most folks will try to help you understand and not think you are accusing them of stealing.
Your point is a good point.
