I am the owner/operator of a children's petting zoo. We were exhibiting at a Balloon Festival in Texas. At the front gate of the zoo is an 18X20 sign that provides a safety warning and release of liability upon entering the petting zoo. We are fully insured. A grandmother in the petting zoo with her children had her big toe stepped on by a miniature donkey. She was wearing open toed sandals. She wants us to pay all of her out of pocket medical expenses, as well as her unused hotel room that night as she elected to go back home and her admission into the festival because she had to leave. The total is $450.00. I am inclined to pay for the EMS fees for the paramedics on site, which is about half of the total expenses, but I think that she has some responsibility in this as well. Your thoughts?
