I saw a KILL BILL Samurai costume man at Sky Tower and a German car outside

I saw a very weird scene today. I went to Sky Tower to visit the top cafe but I saw an Asian man in Samrai costume at the souvenir store. Since he had katana, I followed him for filming. He left to the east of the river. I saw a German car parked in front of the Swiss Embassy next to Sky Tower.

It's more like a sitcom to me encountering German car and such a Kill Bill fireball man.
