I work as an optometrist in optics - I check my vision. One translates and the other translates. According to the refractor, I see that I am completely blind, showing the tenth line. There are many clients, so that I do not take the time to go immediately to the translator, because the patient does not understand my words, "call the top?" The first speaks something in his native language, the translator answers "yes" I clarify "what, yes"Speaks "yes, he does not know the letters"What to do... Include a children's table with butterflies and ships. I say "namely, the top line" Well, the matter went well. Everything is smaller and smaller. It calls. Strange I think. He named it all, and the printing showed great shortcomings. I ask "and then why did you come to check the vision?"And then the translator gives me with a strong accent, "well, why, he doesn't see the necklace! If it wasn’t for me, we’t have told you anything.
