full refunder

A customer that expects everything for nothing, the typical type of consumer (typically buying appliances or electrical goods) that purchases items or services and then expects a business to refund them their money at the drop of the hat for any reason at all. They usually include the threat of contacting government bodies such as the Consumer Watchdog or quoting laws they don't understand out of the Consumer Law without any real intention of following through with it.

A full refunder can also be defined as a person who thinks the world owes them something, that they are always going to get what they want and that every business should bow to their every command.

Mandy bought that television two days ago and now she's decided shes not happy with it and expects our business to take it back and give all her money back! She's such a full refunder.
