Next up in my list are Mobile phone users. Specifically, those who use their phones in public, such as in the street, or on buses or trains, and so on. I'm talking about those who:
- rudely carry on speaking, ignoring other people, while they are being served in a shop, or are buying a train ticket, say;
- walk about while chatting or texting, stopping suddenly every now and then without warning, then look annoyed when someone bumps into them;
- talk at the top of their voice, usually saying some inanity about "I'll be home at the usual time".
