"Do you have any ID?" "For pasta?!" "Yes."

Conversation when ordering food at Wetherspoon's last night:

Me: Hi, is it too late to order food?
Wetherspoons lady: No, no... what table are you?
Me: 318.
Wetherspoons lady: Go ahead, what would you like?
Me: Well I'd like the four cheese and bacon pasta...
Wetherspoons lady: Okay, first I have to ask, do you have any ID on you?
Me: ID?
Wetherspoons lady: Yeah, I just need to check you're 18, that's all.
Me: Erm... for pasta?
Wetherspoons lady: Unfortunately, yes, seeing as it's after 7:30...
Me: ...Okay...? Bye?

Pretty much the strangest conversation I've ever had. 3 weeks guys, 3 weeks until I can get my pasta.
