The fact that you tried to explain yourself and he still kept yelling is learned behavior, so that wasn’t the first time he’s pulled that shit and gotten away with it (but maybe the last). My local coffee shop is haunted by these weekend warriors who love doing laps through the lobby with their neon sausage skin outfits and their clip-on cycling shoes on, so it sounds like they’re walking around with tap shoes. They also keep their cycling helmet on, with the rear view mirror attached. The more people at the coffee shop, especially if there are females, the more clicking/laps you’ll have to endure. No customers means, mercifully, they’re onto a more target-rich environment. “The world is made for those who aren’t burdened by self-awareness.”
