So my buddy comes walking into the store, and sees me immediately.  “Hey, Whack,” he shouts, “Just got out of boot camp, leaving for Iraq in two days, and I just wanted to say hi to you real quick!”
“Dude!  Good to see you again!” I say, “I’m a bit busy at the moment, unless… Hey, do you want to be in a video?  It’ll only take like, ten minutes.”
“Uh…”
I think I forgot to mention that his visit corresponded with the time I was allotted to shoot a training video for the store.
Anyways, he’s a bit confused, but he agrees.  “Awesome,” I say, “Put this hat on.  Your line is ‘Excuse me, but could you tell me where to find the vibrating rubber fist?’”
In this scene, we’re learning how not to be judgmental of the customers.  Our white female employee is playing the clazzic “Goofus” in this example, and her response is to scrunch her nose, awkwardly explain that she’s not into that sort of thing, and therefore has no idea where said item was located.  Then my army buddy becomes awkward himself, and eventually leaves the store.  Our black male employee, on the other hand, takes on the “Gallant” role, doing it right by simply responding “Yes, they’re right over here”, walks the man over, and hands him the product he’s looking for.  The army buddy now thanks the clerk for being helpful, and proceeds to the register to make his purchase.  My army buddy is cool with doing all of this, while wearing a leather hat and trenchcoat.
At no point did I ask him to do it in a German accent, nor did I give him the line “Hans will be very pleased with me.”  He improvised those.
