I personally state on my website that I only see natives of the country that I am working in. Before being called a racist consider this, Firstly I am British born with foreign parents (4 different nationalities if you include my grandparents)
In Ireland it is easy for me to differentiate the rough guys from the gents. Unfortunately I cannot do the same with someone with an unfamiliar accent. I prefer distinguished gents - My body, my safety, my choice. Choose a provider who is happy with what I am not. Its not complicated!
