Is it normal to get angry about things that haven't happened yet?
I recently realized I often get angry about something that could possibly happen but hasn't yet. Today I went to Denny's when I paid for my food I didn't get a receipt. After leaving I imagined they must not have given it to me because they ripped me off so I went to the ATM to check how much they took. On the way I felt enraged and imagined about what I would do to them when I went back to fight over my money. Upon checking the ATM I saw that I wasn't ripped off and everything was fine. I realized I do this about similar events very often. Do most people do this?
