As a stranger to Burger King, why is everything they serve so fucking small ?
Because you didn't buy a Whopper, or a Whopper variant.
Related to Burger King, in the Leicester Square branch, which I visited last night, they've got a refillable drinks machine that contains the following:
Coke Vanilla
Coke Vanilla Cherry
Coke Orange
Coke Rasberry
and
the best bit
Dr Pepper
I went into Argo with a big jug of Dr Pepper.
