At the gym, in the middle of a set. Some dude just walks over and starts talking to me. I can't understand shit because I've got earbuds in and I can't pause the podcast because I'm too busy holding the weight of a small person above my head. I cut my set short, put down the weights, pause the podcast and apologize, ask him to repeat as I couldn't hear him. Turns out it was just some small talk I never asked for. I politely entertain it for a while then he goes away.
4 minutes later he does the same shit all over again. Seriously some people are fucking clueless.
