Cooks are jerks, aka The Gods were smiling down on me last night.

We have one family that comes in. Mom, dad, son about 16-17. If just the dad and son come in, they are awful. Condescending, needy, subpar tippers. It drives all us servers nuts to be talked to like that by someone 5, 10, 20 years younger.
But if either of the two come in with the mom, they are quiet and respectful, if not even friendly. The mother is sweet as pie and they tip better. I had the mother and son last night, which is why I was the luckiest little waitress - the cooks screwed up their order beyond comprehension.
The son always orders "A bacon burger, just bacon, burger, and bun." No cheese, no tomato, no coleslaw, no pickle. French fries and bacon hamburger. I get the mom's order as well.

I take the order out to the table. As I'm setting down the burger, I realize with horror the cooks put cheese on the bun. I immediately say, "Oh my goodness, they put cheese on it, I should have checked, I'm so sorry!"
They both tell me, "Oh, it's not your fault, this happens all the time!"
I tell them they can just switch out the bun, I'll have it back out in two seconds.
"No," he tells me, "I need a whole new burger. I can't have any cheese."
Okay, that's fine, let's be on the safe side. I take it back and tell the cooks they need to READ my checks, and now I need a whole new burger. The one insane cook I've written about before scrapes off the cheese and throws the old burger back on the grill.
"No, no, no - I need a NEW PATTY. This guy cannot have cheese."
"It's fine, no cheese, it's fine."
"No, it's not fine. You made the order wrong, now you're going to make it right. I want a completely new order."
I stood there and watched until I was sure I was getting a new patty. It comes up pretty quickly for a medium burger, and I take it back out. They call me back almost immediately.
"Please don't hate us, but this burger is rare."
"Oh my god. I'm sorry. They were trying to get it out too quickly and didn't cook it enough. Let me take it back, I'm so sorry."
They tell me again it's not my fault, and I take the burger back a second time. The cooks curse and rant and rave, etc. etc., but they do it. I take the burger out again, and tell him to cut into it to make sure before I even leave the table. As he cuts into it, we see the bottom bun. It's soaked in blood from the raw burger, and he looks at me. "I'll get you a new bun."
I have to go back in the kitchen. I have them toast me a new bun. I take it out, apologize once more, and we're finally good to go.

So, by the time he can actually eat his meal, I've had to go back to the kitchen three times. His mom is halfway through her meal. I understand trying to get orders out quickly, but not at the cost of quality. They cost the restaurant three buns, two patties, and mine and the customers' time because they were trying to cut corners. And at the end of the meal, I got the burger taken off the check because it was just ridiculous. The table, again, was wonderful, told me it wasn't my fault, asked if I was sure, etc.

Sigh. I'm going to tell my boss today, because this cook is getting out of hand. He hates his job and just doesn't care. I can't imagine how much our food costs have gone up since he came in. If he can't read the ticket, he makes whatever the hell he feels like, which ends up being thrown away.
