Thanks everyone for your opinions, not sure what to make of them though.
And I thought I was confused before.
I can quite easily go all day without food and I could carry enough water on the bike, it's just that I've always thought of the roadside tea stops as quite an atmospheric occasion, maybe I'm being a touch too romantic here. Perhaps there's more romance to be had in a trip to the Sandbach services!
Mmm, perhaps I'll just go for it and see what happens. Then again maybe not.
