First of all, I'll teach you an opening sentence: Hello, I am. . . . Because. . . So ... . . In order to facilitate. . .

for example: hello, this is. . . Because I saw your family doing activities when I passed by, it happened that our company was doing marketing, so I came in to look for cooperation in order to publicize our store's activities to the maximum extent.

Your second question, how to get the boss's phone number, the first thing to do is to confirm the identity of the talker. If the other person is not the boss, you don't want it. The process of asking for the phone number depends on the satisfaction and trust of the other person. Of course, it is also skillful to increase the chances of getting the phone number.

For example, you ask: Can the boss tell me my mobile phone number? It's easy for the other party to refuse

but you ask: boss, do you prefer a phone number or a mobile phone number? I didn't give the other party a second choice

If the other party really refuses to tell me, it means that I'm not interested. Leave a business card and visit again at the right time

Experience talk+theoretical support. It's too hurtful not to adopt it.
