My gf was having printer problems at her job and I offered to look at it. I worked at a print shop for four years (she has 0 experience). She wouldn't let me because apparently she knows more than me about this particular printer. (I volunteer at her workplace, it’s not a privacy/liability issue). I ended up asking her specific targeted questions that happened to help her fix the problem. She still thinks she knows more than me about it. Sometimes it’s hard to let it slide
I have a PhD in art history and work at an art museum. People love to come in and assume they know more about the art, the history of art, or the museum in general. One time the guy was pissing me off so bad, I asked him where his art degree was from. He said “I don’t have one.” I said “Well I do.”
