Yesterday, i was at a bar and i was flipping coins on what to do and it worked, why or what does it mean?

yesterday, i was a bar. Girls there were hot. It was extremely difficult to choose and i started flipping coins on who to talk to you, if i should talk to, continue to talk to. Apparently, it had better results than if I did it by violition(my own free will). Normally,usually,the girl i pick, will get arrogant,if i show signs that i like her, and will over react and things will become a mess. But by randomly choosing a girl and changing the flow with a flip of a coin, the whole thing came out differently. The girl just wanted to what was going to happen next.There was a lot of anticipation factor and in fact, i was being stressed out, because there was so much expectancy. What is going on through the minds of these girls and why?
