Top one in particular,(1)People who are in the queue to pay for groceries but stay on the phone while queuing/everything is being scanned through...and use a hands free phone while doing it. So rude.
(2)People who pull up in their car to chat to somebody in a residential area but keep the car going/leave the music blaring.
(3)Random people who call to the house but ring the door bell and also knock on the door or bang the letter box. You should genuinely be allowed shoot people like that.
