I was at a local Walmart with my brother, showing a movie while selling food and drink. It wasn't doing well, so a Walmart employee walked by and tried to take some food without me noticing. I told her she owed me two dollars, and she said "yeah I don't give a shit." I went to talk to her supervisor (who I couldn't find) and when I came back my brother was dumping empty food into the employee's cart. I got super angry and started yelling because it was $100 worth of stuff. I ran to a hotel room (which was somehow in the Walmart where changing rooms should be) and slammed the door. My brother came in and told me it was a lesson about how I had to be willing to suffer loss if I started a business.
