Blimey Dave, that bill sounds horrendous to me! I hope they've made a mistake. Do ya live in a huge house?
I don't know if you do any online shopping, but it's worth thinking about it ya know, usually you get the first delivery free of a delivery charge. And you could get a couple of bottles of Grouse (always handy to have one in stock!)
Now I'm not suggesting you're infirm on ya pins or owt, but in this nasty, horrible weather, I think shopping online for ya groceries and essentials is a great idea.
Take care buddy. If ya do venture out, wrap up well. xx
