Sven

This is my kind bus driver Sven.
I spotted his tattoo and wondered what it means.
He told my it is Chinese for " This is not me but this is MCD"
We did some research, if he told me a joke, but these are truly the words. 
Now my mum wants to ask him if he lost a bet :-D
(He has a break of 4 weeks, I hope she remembers it)
