Aimee Toms, 22 of Naugatuck, said she was at the Danbury Walmart when another woman told her she was in the wrong bathroom.
"She said you are not supposed to be here, you need to leave," Toms said in a video posted on her Facebook page Friday evening. "So I said 'yes I do,' and then she flipped me off and said 'you're disgusting' and she storms out."
