A maxim in the retail industry wherein a customer is first priority. The sentence is a logical fallacy because it never assumes that a customer can lie, (They do. A lot.) have unrealistic expectations, (They do. A lot.) make ridiculous demands, (They do. A lot.) or even flat-out abuse the staff member in question just because. (They... Well, you get the idea.) As a result, this mindset has led to many, many, MANY instances of customers acting like entitled jackasses because they think it will get them what they want.

Derived from "Squillionaire," "squill" is a dereogatory term for anyone who accumulates, flaunts, hoardes, or otherwise posseses wealth beyond reason.
