DON'T TALK!
Livia walked quickly to the women's restroom at the far right of the restaurant, after agreeing to Richard's request. Now she was standing in front of the big mirror in the toilet. Waiting while cleaning her hands that are not dirty. Of course she had to do something, or else she would be seen as a freak.
One by one the door to the toilet cubicle opened and revealed a different person. Every woman who came out was questioned, because she had never met Patricia. If Livia had known something like this would happen, she would probably have written Patricia's name in big letters on a piece of cardboard, then held it up as high as she could while waiting for her to come out of the toilet.
Almost ten minutes Livia stood there. However, the door to the last chamber had not yet opened. It was very likely that the person in there was Patricia.
