Stevie Wonder
A few years back I was on a Continental flight from EWR to LAS in F. Sitting in 1A was Stevie Wonder. Being a gentleman I did not try to talk to him as I prefer to respect pax privacy. When we got to LAS I was off the aircraft ahead of him and standing at the gate (special permission) was a limo driver holding up a sign STEVIE WONDER. Now I thought that was a bit curious (Mr Wonder is blind) but then I realised the sign was for his minder who was with him on the flight!
