An insult concept while walking to the office

When I was walking to my office, there was a sliding door that took a while to open. Then, I thought it might make for a good insult or diss. Like someone is so forgettable/low presence/invisible/insignificant that even an automatic sliding door does not open for you. But then, I feel like you could say that the door’s sensor is just faulty, so 🤷‍♀️
