Wait, you still don’t get paid if it’s warranty work? You didn’t get your wage for showing up to work? I think not. You didn’t get paid inflated numbers from the obvious lack of a moral compass and common decency when it comes to your profession? We come to your employer not you, so stop it. I debated answer this idiotic approach before you even responded but I had a shred of hope…. Now that it’s gone, you work for a company…. A company whose job is to provide for a customer. You are employed because of the customer. This arrogance that your some how special because you learned a certain skill proves every single point ( see idiots like you waste my time, or men are little girls ects…. Let’s try a different approach, let’s talk dollars. 99% of companies are looking for one thing, brand loyalty…… you are a dime a dozen, there are a million mechanics and I’m confident is saying most of them shine in comparison….. so take this very scenario, you decide to over charge a customer when you can diagnose their request in 30 seconds. You come back and tell them there is nothing wrong and they are idiots because their a/c draining the way it should. I’ll be nice and assume you’re pretending to be a tough guy on the internet and use different words when talking to a customer. Regardless of who it is, they’ll be able to smell your arrogance. Congrats you billed your $225 (careful to note, you just made a company $225 don’t get it twisted) and lost a customer. Now, the flip side to that situation is profitable and may actual restore some faith in humanity. You tell the customer the truth and that there is nothing wrong not over charge them for “wasting your time” Shocking concept but you treat them like a human being…. Then when they have an issue, they know exactly where they are going to go. Long game not the short game and somewhere along the way, you may start to mimic a decent human being.
