I had deleted my post because I felt like I may be hijacking this thread. Here is the car (Exterior only)I did for $20 today. Changing professions or getting out of business is not an option for me. The detailing industry has too many good people and too many exciting new products to ever change professions. I will just have to keep easing up prices till I find the right price. I have given up many times but I have never given up the last time.
High jacking or not, this is an issue that needs to be addressed. Personally, and I'm not being arrogant, but I wouldn't look at their car for $20. That's insulting to you and your business.
Although, I don't know your day-to-day operations, here is what I do... I let everything go to voicemail. In my message I asked for name, what they would like done, etc..most importantly I said that I will return all calls after my day ends at 7 pm. Regardless if I am working, at school or spent the day at the beach, no calls returned before 7. I do this because it gives me time to screen the people who call me. Once you have their name and number, Google it. All professionals (doctors, lawyers, whatever) have their name online. If you can match their info on your phone to that online, you know they have money and won't be negotiating or want their cars washed for $20.
If their name does not pop up on Google, of course call back, but you'll have to figure out some info on them on your own.
Also don't be afraid to say no. Personally, I would rather sit home not working than wash a car for less than I have listed. Here's a hypothetical situation but what I base my business around. So I would prefer having some retail employee who dives a 2000 Saturn saying I wanted too much money to wash his car than him spreading around that I washed his car for $20. Because....people talk, and that guy with the 2000 Saturn may be a patient of the doctor and the doctor could have reccommended me. The last thing I want is that guy in the Saturn going to see his doctor and saying that I charged him $20 to wash his, but the doctor paid my listed price of like $50. Now you have the doctor pissed off, because he thinks that you jacked up your prices because he is a doctor. That doctor is now not going to call you again or spread your business to his colleagues, neighbors, etc... Personally I would rather have doctor money than retail money.
Of course this was a hypothetical, but it could happen. I treat my work and business with pride, and my prices are as listed unless I state otherwise.
