Think about this. The second floor of the Double Tree by Galleria has a restaurant and bar. The bathrooms are just outside of the elevator doors. I've seen them every day. I've also wondered why they would create a step up to go into the bathroom.
When I got up close the only entry that I could find was the button for the automatic door opener. I hit it and jumped. The door opened to my right. I would have laughed but I was doubling over with stomach cramps from an allergic reaction to bell peppers. For the second time in a week, there were bell peppers in the seasoning. Ahhhhh!
