My convenience store doesn't want customers to owe money, and neither does our store. What else can I write?

Hello!

My family does this:

Get a QR code of Alipay and WeChat, and let customers who have no cash pay with Alipay or WeChat.

Put a sign outside that says, "Small business, no credit."

There's really no way to take credit. The credit limit is less than 20 (tell the customer not to offend the customer in advance).

If in doubt, please ask.
