One time, when I was working at a coffee shop, I went on my lunch break to the bagel place a few stores down where the guy in front of me in line for my usual bagel and schmear wouldn't stop talking to me and asking me questions about my life. Because I'm a nice person, I answered his questions and feigned interest in the things he had to say, but then when I got my food, paid, and went to go leave, he actually FOLLOWED ME BACK TO WORK AND CONTINUED TALKING.
My co-workers refused to believe that this is someone I literally just met 10 minutes ago. Because that would be creepy, right? HE WAS SO CREEPY.
