Adjective. Describes the emotional state of a person who willingly decides to continue doing business with a person or company despite previous experience with that person or company rather than because of it.
The cell phone company finally admitted to their error and credited my account after I spent four hours on the telephone yelling at various customer service managers. But I like my phone too much to switch to another carrier that won't offer the same one, so I'll keep renewing my contract with them. I'm just another pissatisfied customer.
