I was also fired for playing my PSP -
This guy deserves it for putting lives in danger but I didn't. I was fired for playing my PSP. No joke. I worked for a Cable Internet company's customer service/tech support call center. They claimed it breached security and as they were getting ready to suspend me, a supervisor fed me a bunch of nonsense about credit card security and blah blah blah trying to justify the suspension.
I'm sorry but good 'ol Pen & Paper would be much better than the PSP's lacking text input capabilities. Actually, the 90% of employees who brought in cell phones daily could have more easily recorded Credit Card info.
I was escorted out of the building with my PSP & stack of games in hand. I only brought the PSP in on the slowest day of the week when there was often 20 - 30 minutes of downtime between calls. The PSP in no way got in the way of doing my job. Performance-wise, I was actually a really good employee. This happened on the last day of April 2005 and I am still very bitter about it.
Owell, just wanted to share my story.
