Barista: What can I get you?
Me: I'll have a flat white
Barista: what size?
Me: It only comes in one size, the small
B: What?
Me: It only comes in the 12 oz cup size *pointing at the menu*, so I'll have the small
B: What? When did they do that? You should be able to get it in any size!
Me: That's ok, I'll just have the small one
B: But is that hot or iced?
Me: Hot
B: *pushing several buttons on register* You can get it in any size, I just checked
Me: no thanks, I'll just have the small
B: what size is that? Tall?
Me: Yeah, a tall, hot flat white
B: *rings me up* Ok, man, I'll make it for you right now
*proceeds to make the frothiest latte I've ever gotten at Starbucks.*
B: Here you go, man.
Me: uh... thanks? ?
