Walking down the street today and bump into a member of staff at a restaurant we go to semi-regularly. She stops and rubs my belly and then says "how's baby? Can I touch?" WHILST touching my bump. Is this fine!?! I haven't experienced this before but I felt a little...violated? (can't think of a better word) I feel like this is unreasonable and I was too shocked/didn't want to be rude so I just mumbled a response and walked off - what do people do in this scenario?
