My name's Arthur Peale. When I was in high school, my then girlfriend started calling me just Peale. It stuck, for a while. When I moved to NY I got a job as a bellhop. Since the captain called us by name, and there was already another 'Arthur' working there, I opted to have them call me 'Peale.' And it's stuck ever since.
Of course, this has worked against me in the past. At my last job as an appointment taker, I used to answer the phone, "Receiving, this is Peale."
That quickly became quite old with these kinda of questions: "What did you say your name was?" "Excuse me?" "Hello, Peter, I need to make an appointment."
So, at least at that job, I went back to being Arthur. Friends still call me 'Peale,' but family calls me 'Arthur Richard.'
