When we moved offices, John Hannah was filming a scene at Cafe St Honore in the lane behind. I saw him and his screen daughter (the series is set in Edinburgh) but of course didn't get to speak to them.

I have to say, my wife is more of a fan than I am.!

I wouldn't worry about riding your bike home from the shop, but remember it'll feel strange and I think you "grow into" using a bike as you get used to it's settings.

For example, I can always hit the right gear on my own bike using friction down tube levers, but on someone elses tend to under or over change.
