How many of you are in on this?

Custom%
No extra tip added. Most UK restaurants slip on 10 to 12.5% "discretionary service", so check the bill before you tip twice like an absolute hero.
Round it up?
Nobody carries 37p. Rounding up makes paying separately painless, and the extra goes on the tip (the staff will love you).
