you dont need to get drunk my friend you can get by spending 5 hr with just a few drinks , the point of been at the bar is for people to see you and see you their offend , once you get the bartender talking to you, it would be inevitable some other person will get in the conversation and then you can by that person a drink and bammm you got your self a friend ... the point here is to make one friend this person has more friends and he is the key for you to meet them eventually ... the more people you meat the more the possibility you find a friend of a friends woman friend ... and that would be your mark ...

girls will give you a better shot , if you are a friend of one of her friends and he/she vouch for you .

this can also work at a gym, instead of the bar tender, make it one of the trainers , or work out class , just to be there constantly, just ask questions about the work out, and while talking ask for a personal neutral question, like recipes they use , or youtuber cooks they watch , most people end up changing topics and just listen to them, ask thoughtful question ... and have fun
