Yo, Messey. its called open punctuation. Its modern, so it will get to London Fire Brigade in about 234 years. Regrettably, you will not be around then, but the new recruits will still be taught about you and your razor sharp wit. Your new CFO (thats what the geezer wot runs a fire brigade is called, not a CO, which is a gas produced during combustion when there is not enough oxygen for a stoichiometric reaction) comes from the Midlands, so I assume he does not chew gum while he speaks to you (when he comes to you for advice and such like) like most of your compatriots. This is a habit though to which you could introduce him, and on £120,000 a year (which must be approaching what you earn by moonlighting), he can probably afford a packet or two of the dreaded gum.
Best wishes and stay safe out there. Keep out of burning buildings-they are dangerous.
