Tall, Grande, Venti

Transcript
(David is an employee of a coffee shop. A customer comes over)

David: Hi. What do you want?

Damien: I'd like a really large coffee, so...uh...give me the "tall".

David: That's the small.

Damien: "Tall" is small?

David: Yep. Tall is small.

Damien: So what's "grande"?

David: "Grande" means "large".

Damien: Then give me a "grande".

David: But here, it means "medium".

Damien: What the-?! Dude, all I want is a large coffee!

David: Then order a "venti".

Damien: So "venti" means "large"?!

David: No. "Venti" means "twenty", as in, "I just spent twenty minutes trying to understand a stupid menu".

(That's when Damien has had enough)

Damien: AAAUUGHHH! YOU'RE DRIVING ME CRAZY!

(Damien leaves, and the manager comes in, looking confused)

David: I think I'm really starting to enjoy this job.
