I think you mods are lazy
First off I do not do NO scrubbing and skeered of a brush plus I do spray on a wax free.I go in there with my hotwater pressure washer apply my chemicals and charge what is a fair price to me.I do not care what anybody else charges for their wash jobs but I do know what mine is worth and what it takes to stay in business.You'll go out of business trying to wash at another mans pricing,know what it cost you to do a job and charge according.
