Racist in New Zealand.......I am sad

Am I not allow to work in a Swiss Bistro???????
I am Japanese yes, working at Swiss Cafe Bistro with my partner Georges.  
A New Zealand couple came in to our Bistro, sat down and looking the menu for a while, then they stand up and left......without saying anything......( there is a menu outside to have a look.) THIS IS VERY RUDE !!!!  we told them. Then, a man said to Georges, " How come there is a Japanese working in Swiss Bistro !!?? "      WHAT!!?? What is wrong with me????????(I said)  Georges said " She is my partner!! " then a man said " I don't care!! "  meaning, it doesn't matter partner or not anyway Japanese in the Swiss Bistro is wrong...... Am I not allow to work here?????

The another day, we had a little ague with New Zealand woman, she swore and told Georges
" Having Japanese wife is a shame....."  as we told her she was a racist , she said " Yes, I am!!!! "  I can not believe that!

What is wrong in the city center in Christchurch lately????????? Where are all the nice people we used ta have.....?
