Return from UKland

A couple of questions arose from my UK visit.
In no particular order.

1. Can one really be out-Sunday roasted during the hols?
2. Are sprouts mini cabbages?
3. Why are there so many hills in Brighton?
4. Afternoon tea's so expensive so why the tiny sandwiches?
5. England's damp and wet yet no one has decent heating?
6. Where the deuce did all the orange Tango go?!
7. Why is prawn toast only available in the UK?
8. Why are there no basements in UK homes?
9. Isn't moss on your roof bad?
10. Why is there only one toilet for all 4 floors of Harrods?
