It is a personal wish for a technician to add a customer’s WeChat account. As long as both parties are willing, it doesn’t matter. Usually, technicians in clubs or pedicure shops or massage parlors will not add customers’ WeChat accounts casually. Those who can add WeChat accounts think so. You have a good impression of the other party and can chat well. If you add them on WeChat, you think they are worth making friends with. Technicians are in the service industry and the people they come into contact with are quite mixed, so they generally don’t add customers’ WeChat accounts casually
