What should I do if I feel uncomfortable after selling something to an acquaintance?

If it is really too expensive to sell, just give some of it back to others. When it's right, you must find a way to explain it tactfully. I did this just for peace of mind. This proves that you are a good person. If he was a very good friend, he wouldn't be angry. He will understand why you sell it so expensively. If you feel guilty, just give something away and call it a gift. Many shop owners find it expensive to sell things to acquaintances, but they don’t feel bad about it. You will feel uncomfortable, which means you are not a profiteer. In order to make more money, acquaintances will know about it and they will come again next time, but there will not be a third time, and you will lose more than you gain. I believe that this acquaintance will go to your store to buy something next time. You should give him a discount for the expensive purchase first, and then he will charge less for his purchases in the future, so that you will not feel uncomfortable. It shows that you are a responsible, honest and responsible businessman! And unscrupulous businessmen will usually take advantage of the loopholes of acquaintances. This unspoken rule is called "selling goods to acquaintances for money". In fact, this is the most damaging approach to your own name and credibility. No one is a fool. Over time, others will see through you. So don’t treat others as fools! If something like this happens, no matter what method you take, as long as you get your integrity back, you will definitely be a winner in the future!
