I don't go by the customers reactions. I've had customers that have said "Thanks", paid me and left without saying anything more. Thinking they where not 100% satisfied. Only to find out they recommended a ton of business to me. Honestly, I, my opinion only, think it's unprofessional to post anything about the customer. I've worked on some really nasty cars in my time and I never post them up, unless the customer has said it's ok. I keep what goes on between myself and the customer confidential and would never want to embarrass or tick off a customer because of something I told about them. And honestly, in the past, I've had several customers thank me for not talking about how nasty their vehicles are or anything else.
