How to be an oppo promoter? Never worked as a promoter.
Is it a temporary promotion? Then listen carefully to the shopping guide and see how long it will take. First, remember the price and some features. The client came, and I really couldn't cope at the moment. If so, call my sister or brother and tell them what the customer wants to see. You should listen carefully. Don't interrupt, listen to what others say. Make progress next time.
