I never met people like this when I was in school at Santa Cruz (whitest UC) but I met them when I started working at companies that had 20 year veterans. Those are the type of people who cannot say hello to a c-level exec without genuflection and then talk about how society has a "nature-deficit". And yes, they absofuckinglutely do bring guitars, amps, and I've even seen one of those foot pedals before because they need to perform for the FAMILY.
It's really shit, and it needs to be called out. It might be like bird shit where the white part really sticks out but it's still shit.
