Wrong place

So a thing that terrified me back when I was a young child, would definitely NOT terrify me today, or even as a teenager, but as a small child- I freaked out! My dad had taken us to a Go Cart and mini golf place one summer. It was a blast of course, but at some point I had to go use the restroom. I was about 6-7 years old maybe at the time and I went inside and went on in the bathroom. When I walked in I noticed that they had big long sinks on the wall and I had never seen those before. I thought they looked weird but kept on walking to the stall. I shut the stall and started to use the restroom and all of a sudden a grown man walks in and is peeing in the sink and I start freaking out and crying in the stall. He was probably like WTF - lol. I cried until he left and then once he was gone I hightailed it out of there and was embarrassed that I had went into the wrong restroom. I was so scared though- LOL!
