Yes, save the receipt when shopping, and then ask him to return the goods. If there is no receipt, remember to leave evidence, such as turning on the recording on your mobile phone to argue with the boss. Generally, the boss will admit that you are here at the beginning. When buying something, the main thing is to find a way to trick the boss into admitting that you bought it here. The second thing is the time of the purchase. Pay attention to the way you use the formula. For example, you can have a nice attitude and say, "Boss, I bought clothes from you yesterday." , remember me, the boss will usually answer remember, then you can talk about your questions, and then negotiate with the boss. Don’t reveal what you recorded during the negotiation. If it doesn’t work, call 12315. It will be handled in a timely manner. Calling 12315 is a must. There is evidence of purchase, so these recordings are to prepare for the worst case scenario, but I hope it doesn’t come to this. It’s not easy for others to do business, so I wish you good luck~
