Is it rude???

[The D Man]

...to ask a punter what nationality he is? Somebody wanted to book an appoiment for 9 pm but he claims he can't call me until 8 pm because he's at work! Then i asked him what nationality is and... BOOM!! I got 4 texts where he explain me that he has "loads of references" on EI& that i was very rude,and treat him without respect! I told him i just want to know who i am seeing and he told me that i am a racist!! Seriously??

No it is not rude. It is all about you feeling and being safe and comfortable. Some ladies here will not see people from certain nations and that is their right.
