I know that they only employ teenagers, but is there a rule that says McDonalds can only employ friggin idiots as well?

Here is my encounter this afternoon

Me: (in the drive thru after ordering two happy meals for my son and daughter) So which Transformer toy is it this week? If its a new character we will want an extra.
Intercom: Um.. Bumblebee
Me: Na, ya had Bumblebee a few weeks ago. Do you know which it is?
Intercom: (10 seconds of silence)
Intercom: Do you want anything else?
Me: And a large triple cheeseburger meal please.
Intercom: That will be $21.45, please drive through.
Me: Hang on, so did you know which Transformer toy it is?
Intercom: It's Bumblebee
Me: Ok, never mind.

I go through the drive-thru and get the food. Before I even leave the carpark I check my sons Happy Meal and sure enough there is a Drift in it. So I park and and go back in and take the Drift to the counter.

Me: Hi, the guy on the drive-thru said you had Bumblebee Happy Meal toys but its this one so I want to grab an extra one.
Cashier: Oh you want to swap it? Sure
Me: No, I said if it was a different character I wanted another but he said it was Bumblebee. Since it's not I want to grab another one too.
Cashier: Ok, I'll be right back (she disappears into a storeroom)
Cashier: Sorry, we don't have any more Bumblebee's, its just that one.
Me: (irate now but managing not to yell) I don't WANT a Bumblebee! I TOLD the guy on the intercom that if it was a NEW CHARACTER I would want a second! He said it was BUMBLEBEE so I didn't get one. It's NOT BUMBLEBEE so I WANT TO PURCHASE A SECOND ONE OF THIS TOY PLEASE! (holding it up)
Cashier: Oh ok, sure, sorry.

I mean, for frags sake! I'm guessing the idiot on the intercom only knew the name of one TF character so thats what he said which makes him lazy at his job, but she's a moron too. As it is Ive taken to getting reciepts since half the time I order a triple-cheeseburger and when I open the bag half way back to the farm it turns out to be a regular one
