Is the level of education in Russia falling? I live in Israel and work in a store. When I offer a club card to buyers, I say:
You will get a 5% discount!
For the entire purchase? (I am disappointed
Not you, for every thing. (With a proud voice, withholding laughter)
Well, then it is a different thing! Go to!

To the girls who worked with me, I explained long, stubbornly and with a calculator that it was the same thing. I suspect they agreed, but did not believe.
