You've been there 2 days and you know everything already? Sounds like you are a genius. Also, you need to demonstrate high value, flirting with them and giving them attention is what literally other men do, what is the rush? Are you desperate for sex?
This what I call a loser mentality. If that his job then fine. Be the best doing that, make connections with customers, find ways to save money to that company or bar, be a fvcking winner. Learn how what other above you do, so you can cover them when they're off. Ask the boss where is the help needed, accounting, financing, marketing, be a go getter. You might start as restocking bottles, but with a great attitude towards the job, towards customers, towards the business, can make you a shift leader, then manager, and later managing multiple restaurants. Then with that experience, you can even start your own restaurant. People today have no aspirations, pathetic.
That is the winner mentality, not doing the bare minimum for a job. That's why us immigrant kick any american born citizen's a$$, because we have the mentality of being winners. This guy and probably you don't take advantage of opportunities, and you see a hot girl and your whole world comes crashing down chasing puzzy.
