I'm assuming your target audience is every guy? Basically meaning in your story, you have your salesman that's a nobody; an empty shell, who every guy can connect with; wakes up, goes to his boring ass job, comes home, probably talks to maybe one or two close friends, and then, goes back to bed. Then by learning routines; sales stuff, thus this guy become mpua, something that any guy can do, making the normal boring guys dream of seducing models a reality?
Anywho, if the above is true, the oneliners you are looking for would be questions that elicit information that can be used on "this bar chick" which should be shown earlier in your script that the salesman learned in his... sales training?
Examples of elicting and using info can be found here:

or with a quick google search of just the two terms: elicting pua
And if you're looking for a main actor..... You should definitely give me a call
