When they fuck up, call the resturant, ask for the manager and explain what happened and how it went wrong. Be polite, but let them know they fucked up.
The manager can't do give remedial training, can the worst employees, etc unless they are aware of how bad things go.
If the manager is unsympathetic, and you've been polite & reasonable then ask for contact info for the stores general manager or the regional supervisor.
They want your business, and they know that if they fuck up too often they won't have it. Close the feedback loop and see what happens.
They always fuck up my orders. I'm done with them.
I went through the drive thru, ordered a 3 piece chicken strip meal with mashed potatoes and gravy and mac and chee. They asked if I wanted honey/butter for the biscuit, I said yes. When I got home, there was no honey or butter. Oh. And no biscuit. And instead of mac and chee, they give me some beans or something.
How fucking hard is it? I mean, they managed to enter the order correctly, everything on my receipt was correct. I typically check my drive thru orders to make sure they don't screw up, but there's only so much you can do... as in, I see the box where the chicken and biscuit should be, check, I see two containers for sides, check.
Seriously, I think they're at under 50% percent success for getting me the correct order. And it's not like I make huge orders for an entire family. I am ONE FUCKING PERSON. I order ONE FUCKING MEAL.
The McDonald's next door never screws up my order. The taco shop never screws up my order. In-N-Out never screws up my order (though to be fair they pay a couple of extra bucks an hour so that they can avoid hiring the most useless of the useless).
And why is it that all the fast food places force their drive thru monkeys to open with some script to the effect of "Would you like to try our brand new blah blah blah today?" It would almost make sense, except that they universally just mumble whatever new item they're trying to sell you. I can never answer yes to their question because I DON'T KNOW WHAT THE FUCK THEY'RE SAYING!
Fuck you KFC. You're a bottomfeeder, even amongst other ghetto ass fast food joints. I hope your parent company Yum collapses in this economy and your blight is lifted from the world.
