Who is Number One?

Pez came to find me at work and we had lunch together. That was good. Otherwise, today has basically been really surreal.

Liz: *working at till six* *presses the little CASHIER NUMBER SIX PLEASE button*
Customer: Hello, number six.
Liz: (...I'm not a number! I'm a free man!) Er, hello! Would you like a bag!
