I just got a large coffee.

When asked if i wanted room for cream I said "Yes, two fingers is fine please."
What I got was a small coffee in a large cup.
I should have clarified (in my american colloquialism) that I intended the attitude of the fingers to be horizontal not down the cup.
My bad. I will speak English next time. :)
I decided that the cream was actually more valuable than the coffee so I topped it off, took it home and ate coffee flavored corn flakes instead of drinking it. 
That's how us hustlers roll.
