Had the dumbest customer ever at work today. Bit of backstory, it's a car wash and whoever designed it didn't bother to put in a proper fan. See, when it's cold as fuck and you open the door to a fairly warm and very wet wash bay, fog builds up pretty quick, and too much of it will block the laser sensors and make the whole damn thing not work. As you go in there are some sprayers on the floor and walls that spray at you while you drive through, and then you stop and the wand travels around your car.
At temperatures like today's (-20°C and below), it takes anywhere from a minute to 5 seconds for the fog to get thick enough to be a problem. So this woman comes in, and when the door opens, she pulls in until the sprayers start and just stops. Puts the fucking car in
park and just sits there. These stop spraying after about 30 seconds, and she just keeps sitting there. In park. Staring at the big glowing green "DRIVE FORWARD" sign.
After about 2 minutes of this (and I have no idea how it managed to run with the door open for this long without the fog causing a problem) I have to actually go tell her to "keep going". She doesn't understand. "Keep driving?" "Yes /*
you fucking moron */." She craaaaawwwwls forward at a pace that could barely have kept up with a tortoise hauling a load of bricks, taking another whole minute to drive the 2 meters or so until the "STOP" sign lights up.
I honestly have no idea how the machine managed to tolerate this despite A) the fog being as thick as Bush and B) it being set to stop after 3 minutes of waiting.

But what really baffles me is what the fuck is so difficult. People see this big green glowing sign that says "DRIVE FORWARD" and what do they do? Stop, back up (this one is quite popular), get out and ask for help, now even just put the fucking car in park. How in the fuck did these people pass their drivers' tests?
Also, I wasn't exaggerating when I said it can take as little as 5 seconds before the fog becomes too thick. There was one last customer 15 minutes before closing time (there always is), and that's precisely how long it took. Needless to say, actually getting in within 5 seconds is impossible (especially given about 3 for the door to open far enough for a car to fit through), so I just gave them a refund and closed early.
Why do people think washing their car at -20°C is a good idea, anyway?

Hey, let's go soak the car and then drive it around at well below the freezing point of water. Yeah, there's a blow-drier, but we all know those never actually get anything more than half dry.
