i work automotive myself... we have a nice LED sign about 2' x 6', scroll message of how long the wait is for Oil changes, and also one for Tire Work... right there behind that cashiers desks where you go to get yoru work order written up.

well.. 3hr wait.. its a busy saturday, this old heavy set gent wants 2 new tires, and he has his wife with, and her car, which is getting a flat repair.

not even an hour goes by, and the guy complains on the waiting time.
over, and over
and over...

finally got his car done and pull his wife's in.. now, being two different cars, they are on two different tickets... and the guy thinks they are both done, even tho his wifes car is up on the lift.

he pays his ticket thinking he paid for both, bitches about how his wifes car is up on the lift, tire not even off.

I grab my manager, a real pro at this stuff.. he lowers the car, and drives it out of the bay, with the tire still flat. one of the workers took out the small portable compresser and filled it the tire to the usual 30-32 psi.

my manager tells the guy straight up, the sign says how long it will be, the contract you signed.. ours and your copy says when its expected to be done (about another 20 minutes from now, which a flat repair is 5-10 minutes if that). the contract also states that by signing you agreed to our services and the payment, etc. and being that you didnt pay for this car yet and if you want to go off in a hurry, we can cancel that order and let you drive it off.

that guy got furious and left cursing and shit.

I see how some customers can get on your nerves, but when theres legal binding papers signed and dated by the cashier and the customer, they really have no say unless we breach the contract. (if we go over the time expected, blah blah 30% off, etc.)

I just wish I was able to clock out, change clothes and fucking hock a wad of snot at the fuckers car as he left tho. it'd of been much better.
