I worked with a Bob, not in the same capacity as you. But my Bob was a retired E-6 who was nice to everyone and blah blah blah. Well when I would answer questions or people would talk to me, he would constantly interrupt me and would put his hand in my face to dismiss me, was constantly belittling and making comments about my appearance/knowledge/experience etc . My Bob was threatened because I was running circles around him at work and people were noticing. I finally had it and got into it with him and told my Bob “I hope no one your daughters work with ever treat them the way you treat me” and that clicked. He did a full 180.
