I did this same thing too in first year undergrad (first year alone in a strange city), and then I realized that I was an idiot. Clearly people hook up all the time, so the probability of meeting someone isn't that low. Key difference: people who want to hook up put themselves in situations where they meet other people who want to hook up. The probability of me meeting a fruit vendor is the same if all I had to go on was total random probability of meeting strangers, but instead I just go to my closest grocery store which is conveniently located 80 metres from my house, and then I buy some fruit.
