1) Chuggers (slang for "Charity Muggers" - the people who try to get you to sign up to a regular donation to a charity there and then on the street)
Are you a chugger? I know you're probably a good person. One of my friends used to be a chugger. I know you mean well but you interrupt my journey all the time. Sometimes I deliberately try to chat you up to put you off. Sometimes I try to pretend my iPhone headphones are glued into my ears and I'm off to the hospital to get them removed. Sometimes I JUST WANT TO GET TO THE SHOP TO GET A SANDWICH. Please let me have my sandwich. Especially on prawn day.
2) People walking along the street and then stopping suddenly
Are you that person? It's probably because you just remembered that you left the iron on or that you suddenly realised that you really CAN taste the rainbow when you eat Skittles and that you may have synaesthesia. Either way - STOP IT. It's a horrible habit and you cause accidents. Cars aren't allowed to suddenly brake for no reason so please don't perform an illegal emergency stop just outside Dorothy Perkins.
3) Loud arguments
Ok, I get it that people fall out. I understand that emotions boil over. Is it really too much to ask that people restrict these exchanges to a sound-proof room? I think not. If you're arguing in the street about last night's starter being poorly presented or some other trifling matter then have a sharp word with yourself (although why you'd want a trifle as a starter is beyond me). Let's keep social dialogue to friendly banter about the weather, the creative arts and if you really, really must then something about sport.
For the sake of better streets the world over, let's look at a complete ban for all three. I know this is only my opinion, but it is also, when you look at it objectively, completely right.
