Clustomer 

When multiple people enter an establishment to make only a single transaction, unnecessarily complicating a simple job by sheer weight of numbers.

Five students holding a table by ordering a single beer; that's a clustomer.
I'll call you back, a clustomer just walked in. I'll need a drink after this.

clustomer 

A difficult customer; one whose actions or reactions to price, organization or just reality in general makes planning and execution infuriatingly difficult. That is, a cluster-fuck generating client. Also most interior decorators.

We could have done this six-week remodel in two weeks if we'd had a regular guy instead of this friggin' clustomer.

Massive cleanup on Aisle 6 -- clustomer at work!

Clustomer 

A misguided customer by their actions or by any part of an action that they are responsible for, that has caused an enormous, near indescribable mess of mass proportions, which, as of now, best describes them.

Oh man! I was dealing with this Clustomer today that must have had their head on backward.

I am not sure how long it will take to clean-up the mess that they made or undo the things that they did. It would easier to just start over but we have already spent 3 days trying to explain that they are doing it wrong

Clustomer 

An individual, group or company that employs your services but has no clue about what they need and have the tendency to always mess things up.

Bob is a nice guy, but is our worst clustomer.
