Trailer Villa RV Park

Came to dump our tanks. Arrived at 4:45 or so. Paid to dump... Then dumped. While were filling up our water tank and organizing our outside storage, a woman came out of her house looking visably angered. She walked up to me and told me that I should not have been here, because they stop allowing people to dump at 4:30 and that I needed to have stopped dumping by 5 PM. I told that I had stopped dumping a while ago and were just organizing and filling up. She then told me to hurry up and leave and walked away. I looked around for signage about the times ... Nothing... The website only says that the dumpsite closes at 5pm. After about 5-10 minutes the woman walks back out and puts up a sign that says that the dumpsite is closed. At no point did this woman tell me that she was the manager, I had to ask. To put this into further context... I am a black man and she is a white woman. I will not go back to this RV park, nor should anyone else as this service sucked. I don't know if this woman is racist or just plain rude, but this entire situation could have been handled much better.
