Security gave me the number to Risk Management. She was very empathetic & told me that my jeans would be replaced. She took a picture of my jeans and bagged them & asked if I wanted them. Security, was very helpful at that moment in time. I called my friend & she got security to come to restroom. I called my husband, who was standing outside of restroom & told him that blood is soak into my jeans & I can’t put them back on. I had been exposed to a stranger's blood. At that moment I the cleaning lady said 'Is that your blood?' I said 'No.' She said 'Stop touching it! Wash your hands!' I got nervous & stressed out. I put some water straight from the faucet on my jeans, it was rinsing out & you could see a red color.It was blood. I went into bathroom & I saw a large brownish colored stain. I thought I sat in water that must have been soak into the clothe van seat. After shuttle ride I got off the van & immediately felt dampness on the back of my left leg. Sat 6-21-14 my husband & I checked in at Two Trees Inn.
