Some car owners chose convenience over quality

We live in a time whereby most people expect instant service

 20 years ago a customer would wait 1-2 hours for a return call and today they lose patience in 3-5 min's and call someone else.

Instant service is often more valuable to the customer than quality service.

The question  begs would the market support a $40-$60 surcharge to bump to front to the line and get instant service, for many customers I think so.

Some franchise shops have certainly caught on to the fact that if they leave open space for walk in customers that they get the customer based on convenience.
