5. The Contortionist
These clownish fumblers always insist on sprawling their change back onto your counter and putting everything away in a specific place before they move out of the queue. Their limbs flailing as if youve just given them many flaming hot potatoes, they perform a range of labyrinthine arm movements accompanied by grunts and groans as they struggle to handle that sticky combination of a few coppers
and a receipt that youve given them. Youd think over the age of 10 theyd have gotten used to the old hand-eye coordination concept, but as becomes increasingly evident in retail, the public drop a good 100 IQ points upon entering any serving scenario.
