I recently opened a business doing mobile RV maintenance and repair. I just returned from a call where a young woman and her infant child were living in their RV and the AC stopped working. The problem turned out to be their converter and the part alone costs $455. She doesn’t have the money for it. She waited until after I spent an hour diagnosing the problem to tell me. Thankfully I didn’t order the converter. How do I make sure that this doesn’t happened again. How can I ask if my customer if they can afford to pay for my service? If she had told me from the beginning that she couldn’t afford to pay I still would have diagnosed the problem for her and her baby and just wrote it off.
