Mono Monday - Annoys Me

The Mono Monday challenge today is anything that annoys you or makes you cross. 
Generally this is things like people stopping suddenly or not looking where they are going because their head is glued to their mobile phone. Or blowing cigarette (or vape smoke, why are they inhaling cheap air fresheners?) in my face. Or feet on seats. Or litter. Or, wait, I realise I am really easy to irritate. 
Today's winner though is loutish behaviour. Or laddish, whatever it is, it's annoying.
