A couple of mine:

1) People who talk to themselves while shopping on the same aisle as me. Yesterday in a HomeGoods, an older lady next to me was going on and on to herself about her choices of decor she was deciding on. Lady, it interferes with my concentration and my shopping experience when you are having a full-on conversation alone. To no one but you. I notice this a lot. I want to be like, "Do you know you're saying that out loud?"

2) People who take an entire decade to pull in/out of a parking space, all the while totally holding up traffic. If they have to do the whole forward/reverse thing more than a couple of times, I want to personally take their license away.

3) People who think it's okay to take 5 minute breaks on machines at the gym while they check their phones and send texts/emails. Obviously it's always on the machine I'm waiting on. This I have the least patience for, I don't want to be at the stupid gym all day...So I have started tapping people on the shoulder (they always jump bc they're in their own little iphone world on my machine) and asking them how many sets they have left. Then I stand right there and stalk them. This always makes them move faster, probably bc they're uncomfortable, and I care not!

What are your random pet peeves that don't harm anything but drive you nuts anyway?
