In my years in the Hospitality industry, selling things on eBay, and doing Free Lance work, the one thing I’ve come down to is that people that spend the least amount of money or get the biggest discount on a product/service will expect the most and take up the most amount of your time.  A perfect example of this is when I worked in  hotels.  The people that stayed at the hotel and paid full price for their room were courteous and didn’t burden the employees at the front desk or the rest of our staff.  Now the people that got the hotel room on Hotwire or Priceline for $30/night, they were ornery, demanding, and didn’t tip.  Obviously there are exceptions to the rule but there is one thing I want you to take from this:

“If you have a cheap service, then you will get cheap people that will eat up all of your time.  If you have an expensive service then you will get an evenly balanced request of your time”  

The core issue of the quote above is that people who are always driving for a bargain and pushing to get every penny out of every service have time to pursue it and ergo time to bug you.  Someone that has a higher budget typically has better things to do then to try and take advantage of the service/product.  

One stipulation that needs to be made is that the above information assumes that the product or service that is being presented has value and isn’t cheap.
