Woah, deja vu. I posted another thread like this today on the same topic. I'll just copypasta what I said.

Ok, so I go for lunch today and decide to have a baguette. £2 for a baguette, complete with turkey, salad mayo etc isn't bad, especially when you consider it's freshly made. So, I patiently wait in the queue for my sandwich for about five minutes. Then, aware that I speak quickly and have a tendency to mumble, I slowly and clearly, but not patronisingly, explain to the woman at the counter what I want.
"Can I have a Turkey, Mayo and Tomato baguette please?"
She then pauses and replies hesitatingly
"Uh, Turkey, Mayo and Tomato?"
"Yes."
She then spreads the mayo on the sandwich and puts the turkey on while I pay. Lo and behold, when I get my sandwich, I find that it is covered with lettuce. Now, I dislike lettuce, quite a lot. Which is why I did not order it. But, for some reason, I have lettuce on my sandwich. And I'm pissed off. Not because I have lettuce on my sandwich, but because I explained what I wanted, extra carefully, and then repeated it to confirm, and yet she still comes up with the notion that I want goddamn lettuce on my goddamn sandwich!

Alas, due to it now being inedible, I threw it in the bin. So, I'm two quid out of pocket, and with an empty belly.
