What is the name of your state? This is in the state of California. I was using one of Costco's motorized carts and I put my purse over the middle post of it. I went to stand up to look at something and I stepped off with my left foot. I went to step off with my right foot but got it caught in my purse and I tripped. I fell on their concrete floor and broke my left ankle and smashed my right shoulder. I know it was my fault and Costco has tape of the accident showing that. I am wondering if I have a case to have them pay for my injury.
