The dwarf approaches the counter. It’s very high up, so he can’t see the other side.
He tries anyway and says: “Can I have a Coke please?”
He tries to jump as high as he can, saying “Can I have a Coke please?”
He jumps up and down, saying every time he gets to the top, “Can I have a Coke please?”
(still no answer)
He’s fed up, so he goes around the counter, and on the other side…
…he sees another dwarf, jumping up and down saying, “Is Pepsi OK?”
PS: Google tells me that “dwarf” and “little person” are equally non-offensive. Feel free to educate me if it’s the wrong term.
