I'm a manager at a place where customers have to drive in and out of test bays to get emission tests done.

We have four little ticket booths out front that a customer has to take a ticket at, then a tester will direct their car to an open lane. (The ticket is for time tracking purposes, so the bigwigs can make sure folks aren't waiting for too long.) Also, the entrance to our property is a small area that opens up significantly.

So one day a customer pulls up to a booth, but the empty lane is not the one they pulled up to. No big deal, the ticket system is centralized, you can take a ticket on one lane and be tested on a different one. But the customer decides to play musical chairs and back up and twist to get positioned at another - a van pulls in behind them and slams on their breaks in the entrance, because holy shit this fucker didn't know how to use a clutch. It was a manual and the dude just dropped his left and slammed his right before almost hitting the guy behind him.

AND THEN he does the SAME THING, BUT FORWARD! Motherfucker screeches up to the other ticket box, takes a ticket and peels towards us like he just got his flux capacitor working. Fuck. That. From hearing his aggressive maneuvers, we now had another tester rush out and both him and I were yelling at this dude to slow down.

He pulls into the bay slower, and I stand behind a corner unseen and listen. Test goes by fine, my coworker hands me the test result (he didn't want him peeling out of the building like he pulled in), and sends him around to the office to pick up his results.

I intercept him before he pulls into a parking spot, paper in hand, and walk up to his driver's side.

"You know, if you were rude to my employee, I would've kicked you out before getting your test done."

"I- I wasn't?"

"I know. And thank you for that. But I was this close to not letting you be tested after that entrance here. You almost hit another vehicle, doing that."

"...A-ah."

Hands paper over. "Your vehicle passed. Please drive more carefully."

Customer proceeds to drive slowly off our lot.
