I have a sister who used to sell things at home. Because it is food, sometimes people will eat first and then owe money after eating. It's normal for you to say that, but you always owe it, aren't you a little? I remember it was because someone really owed more. So when he came to dinner again, my sister slipped in and said, who knows what you can owe you if people are directly angry and say no money! But you did it! Small businesses are most afraid of people who owe them money!

Bitter!

Sometimes it's a little trivial, but everyone knows what you want to promote! Because my sister used to sell clothes when she had nothing to do, because the clothes were a little more thread, so it was not easy to sell, but it was good to sell them cheaply, and the sales volume was not bad, but I was afraid of encountering clothes that I didn't buy, and I had to talk about how poor the quality of the clothes was. I think I'm afraid of meeting such a tangled person in business!
