IRDG

Short for Impatient Refunds Department Guy. This is a guy within your company that does refund authorizations, but doesn't want to bother with trivialities like security verification. The only difference between him and a thief is that he only asks questions appropriate to the process of returns, and will not ask for the entire card number or the number off the back. He doesn't have time for small talk, or even common etiquette. Example:
 * Me: "What is the customer's name?"
 * IRDG: (Sigh) "I am trying to do a refund!  How much did the customer pay for this item?"
