I am replacing a 11 year old laserwash with one I have had in storage for 8 years. Putting in virtual treadle, new led signage, countdown timer and bridge cover. Also updated the building outside an inside. My question is should I have an attendant to clean tires etc? Or does anybody have a self serve tire cleaning area? If so whats the best way to set it up? ( the old one didn't do enough business to support a attendant ) If I did have an attendant how much should I pay them per hour since they get some tips? Sorry for all the questions but just do not know which way to go.
