I have a 'phone from a well known manufacturer, and I got a job with a
company that supplied them chips. It so happened that the Christmas
before I started they'd had a major panic, and several people had spent
Christmas in exotic climes (No, it wasn't Apple!). It also so happens
that this manufacturer had used the same tone on their internal security
doors as for the incoming SMS tone on the model that I have.

I had to change the tone. People were getting flashbacks
