Tanks on your answer, I think that these will be helpful in my work. So the best thing is combination of methods. And I really like the mirror thing, because my first contact out of clinic was buying a newspaper or order a cafe, and this is great first exercise. What will you prefer as a first contact better: phone conversation (smth like cinema info) or going to some calm cafe and order a drink? P.S. I am not English native, so sorry if there are some grammar mistakes
