This one time I was at work and I was in the bathroom washing my hands, when this one lady peeked her head in the door and asked me if she could come in because the women's restroom was being cleaned and she couldn't hold it anymore. I was like "uh..." trying to think of something to say when she just came in and went into the stall. It wouldn't have been that big of a deal, except for some reason she felt the need to carry on a conversation with me while she was doing her business
