What's amazing to me about that anecdote is that it seems like such a tremendously small reason to dislike unions, for all they do to improve worker safety, pay, and provide a stop against exploitation by corporate owners. I would consider not being able to plug in my own gear at a trade show a small price to pay to show my support for unions and union workplaces.
