This is why I'd not survive a day working in a bookshop :)

I've always liked the idea of running a used book shop-cafe though, where you could get away with browsing, see a lot of old favourites but make money on the coffee. Also because frothy coffee goes well with a book as long as it's not spilt ;) but damn customers who'd want actual serving when you got to the good bits! .....'your coffee will arrive as soon as XXX finishes XX XXXX!!!!! now shush'
