klutztomer 

A horrendously-clumsy aisle-browser who habitually wreaks havoc and chaos with a store's merchandise and/or display-shelves due to his brainless bumbling into everything in his path and his butter-fingered mishandling of the items he's looking at.

Archie Andrews seems to always make a mess at the local supermarket (especially if there are attention-distracting cutie-chicks among the other shoppers) no matter how careful he tries to be, so nowadays he usually just heads straight to the klutztomer-service desk and asks them to gather the items he needs.

klutz + clusterfuck: a clusterfuck caused by someone being a total klutz

The waiter tripped over the fold in the carpet, knocking over the wedding cake and spilling all the red wine on the tray all over the bride's white wedding gown as she gave her speech, causing her to scream into the microphone and make every guest's ears bleed. It was a klutzterfuck.
