I dont think techs should be in charge of of have to check up on or any form of.Thats what a supervisior is for.Yes the customer is the end consumer but you and I both know mister customer can screw himself due to lack of knoledge.It is the techs job to keep him informed.John Q Customer mostly sees the end bill.You dont let him know its time to tune lift up,the plugs gall the head and now hes in for a repair that could have been avoided.Cost of tune up in no way could equal the cost of engine repair.A lot of repairs I see could have been avoided if simple maintanace had been done.So even though one tech can save cost per month Ill bet my bottom dollar overall cost will be unreal.Some customers dont want to see you come in because you find a thousand things every time you show up behind regular tech.Its in my view that a supervisior should keep an eye on all his men and let them know what they miss.A tech has no power to correct a sorry tech. Some want to hear what others have to say some just want their 8 and home.I want to provide the best service to all my customers so they wont even look your way when you come calling.
