While it is possible, it is very unlikely that the same technician has worked on 5 cars that morning.
So what is the chance here that he confused my car with some other cars?

I'll be devils advocate here as I've worked in the service dept of a dealer. Techs will usually work on 2-3 cars at the same time. When you are at home and you change your oil you are only working on one car. At a dealer they want to be...ahem... efficient so while your car is draining oil they will be working on a timing belt or whatever on another car. This means a couple of things: 1) It's real easy for a tech to get confused and it take longer to do the one task even though over all they are being more productive for the dealership, 2) It's real easy to make a honest mistake, 3) It's real easy to confuse what you did to what car.

I have yet to see a dealership that doesn't operate this way.

It is not uncommon for techs to cut corners when working on 2-3 cars and skip serviced that they feel (arbitrarily) are not necessary. Techs that don't skip stuff usually don't keep their jobs (why I left the industry).

Are all dealerships like this? I hope not. But most of the ones in my area are like this.

So if I were to guess, the Tech was told to change the oil and rotate the tires. Oil changes are noticeable (color) so that was given priority. After 45 min. of doing something else he refilled the oil and quickly visually inspected the tires and saw they looked "fine." He then released the car.

That's assuming everyone is being honest.

It's good the manager actually followed up after you embarrassed him. It's too bad that's what it took. I'd be more concerned about the interaction with that manager than the tech. The manager handled that exchange with you poorly,

Novablue, thanks for the input. I suspected they are multitasking too. I understand about efficiency and have no problem with that as long as it doesn't sacrifice quality.

There are a couple things about the dealer that bothers me:
1. They don't understand what the Prepaid Maintenance Service means. It means that customer and SOA and its dealerships already agree for a set of service to be delivered for a specified amount of money already paid ahead of time. If the service is not needed, but no harm would be done if it is performed.., just do it.., because they are already paid for. No excuse to skip it just because is not needed. I already paid for that labor.
2. They are hasty. If they cannot communicate a simple thing like that.., like the other poster said, do I want them to work on my engine on more complicated stuffs ??? Again I understand efficiency, but not at quality and safety expense.

I wouldn't even let them change my oil.

Find a good indy shop near you. Ask people you know and forget the dealer.
