Why are some people so SPIRITUALLY selfish? Why? What's the matter with them?

I went into a Deli on Eighth Avenue and told the Korean guy that I needed change in my life because I was feeling existentially thwarted and he yelled at me! He said: CHANGE ONLY FOR CUSTOMER! I was so overcome that I burst into tears and then he pulled a baseball bat out from behind his counter (I thought it was only Japanese who like baseball...is it Koreans now as well?) and I guess he thought I wanted to join his baseball team but then I thought that he might be one of those cultists who was trying to abduct me to get me to sign over my trust fund and then make me peddle stuff at the airport which I would really hate because airports aggravate my nervous condition, (esp when I don't have my Xanax) so I ran out of there and came to work and now I'm here but I am too upset to work. I think I should just go home and get back into bed. But why are people so spiritually selfish?
