Sometimes customers deliver. I work in a jewelry store, always behave very polite and welcoming, although there are different people. I got an offer for my whole life.
The buyer chose two chains, looked at them, criticized them and said, “Give them to me for a hundred dollars.” You will both pay and I will pay you in cash.
"Sorry," I say, "I like you very much as a human being, but I sell you a chain for $84. And the second, for 120 U.E. For a hundred, I can’t raise my hand.
Make a significant discount!

Dear buyers, a) learn mathematics b) have conscience.
I love you.
