Door-to-door sales, taking the owner into the door, how can this property company put an end to it?

I think the most important thing is to be able to quickly identify the owner, that is, how high is your recognition rate of the owner. If you are sure that he is a salesman, stop him. If you want to put an end to it, the key depends on the sense of responsibility of the staff in this position. Therefore, it is essential to constantly give them necessary safety precautions and customer etiquette training.
