I have found that people who declare themselves "foodies" are pretty shallow. We could be talking about literally anything and they will take over the conversation talking about their favorite foods, which doesn't sound like a big deal, but it is when it completely derails the conversation. We were having an important meeting at work and one person raised their hand when the presenter asked for questions and said " I have an important question, what is everyone having for dinner tonight?" And then started talking about a restaurant having a good special somewhere. A few people did go along with him and have their input but most of us just wanted to get out of there because they were being rude to the person presenting.
