Some quick help, How would properly number close a customer at your job?

Your strategy to number close is completely dependent on the type of job you have. If you work at a clothing store your strategy would be completely different than when you work at a restaurant.

Be specific about what you do and how much time you generally have to chat or something

I work outside i bring carts from the lot inside...so i tend to have a long period to talk

Well great,

First of all when you're working you give off another vibe than when you would approach her in normal clothes as a normal passenger (i assume you have working clothes)

Because you have a lot of time to talk it's a typical daygame situation but she might be busy. You should watch some youtube movies from sasha daygame or james marshal or yad. They all have completely different styles and you have to find out for yourself what kind of style matches your personality.

I'm not going to explain how to number close hb's while working. But if you follow typical daygame you should get there.
