Here's one from when I worked at Subway.

The worst sandwich I've ever seen was from a pregnant lady (Important, because it's the only explanation on why she wanted it).

She ordered a footlong Steak and Cheese. Pretty basic, everyone gets them, they're good! As I'm putting it together, throwing the cheese on top, I hear her say "What's that?"

I look up, and see her pointing at the Seafood Sensation, which is fake crab and mayo mixed together. I tell her what it is, figuring she's thinking of getting it another time.

But then, she says it. "Can you put that on top too?"

I don't really know what to say. I mutter "On...on top of the steak?"

"Yeah. That sounds good"

"I mean...sure? You wanted to the steak toasted though, right?"

"Yeah, but just toast the whole thing. Crab and all."

So...I do. I put fake crab and mayo on top of a steak and cheese sandwich...and then toast it.

The smell that came out of that toaster when I opened the door still haunts me to this day. It was just simply foul. But, the customer is always right.

She asks for a few veggies, I believe she added chipotle sauce too it as well. Wrapped it up, and she sat down and ate the whole thing. She was definitely a satisfied customer.
