What "Appointment" means to me is that if you do not show up you get billed for Missed appointment and service should start within a reasonable time, Usually one hour.
How long it will take depends on what's wrong.. They might look at it and say "one hour" or "5 Hours" or "This evening" but when they get into the job it's an "Oh-****" event there is a whole lot more needs to be done.
And then there's the odd case of the "Oh **** we backed into it and now have major body work to do"
True Story: Man got in a traffic accident (Car) took it to a body shop that was next to where I worked..
They put on the new fender. Painted it all up. backed out of the paint booth to move it to the drying booth... FORGOT TO OPEN THE DOOR FIRST
Dear sir: There will be a slight delay. no additional charge.
They replaced the fender AGAIN, painted it up. parked it at the curb and the shuttle truck that was backing in BOBTAIL to pick up the shuttle trailer from the warehouse where I worked to the store....
Dear sir: there will be an additional slight delay. Though this time there IS an additional charge you won't have to pay it for the moving company will.
I kid you not. Really happened.. I witnessed the truck hitting it.
Home was where I park it. but alas the.
