Is it weird to have a conversation with some when they are in the bathroom (toilet)? I dont have an issue with it at home, its the perfect way to corner my DH when I want to ask him something lol!!
BUT at work? A lady at my work does it and I think its weird/uncomforatble
I'll talk with DH if he's in the bathroom cleaning his teeth or having a shower, usually just to ask a simple question, not for a full conversation that requires in-depth thinking.
At work, if I go in to use the toilet (ie. in the cubicle), I don't expect (or want) to have a conversation at the same time. Unless someone in the next cubicle is asking me to pass them some paper because they have run out.
If someone is trying to initiate a conversation, I respond with one syllable/one word answers. They get the hint. Or I just say "Wait until I get out of here and then we can talk."
Once the director of my company did this to me, that was not OK. The man has many issues with boundaries, not sexual or anything just in an over sharing kind of way. Though can make the work place entertaining, especially with new staff, after a while we get used to it and he doesn't come in that much anymore.
I'd let him know that I will give it my full attention once I have finished my business and I'll find him in the office after I have finished in the bathroom.
Your male boss followed female staff into the female toilets??? What the?!
