How about "The Law"?

[Birchy]

And by that, I mean all those little rules and regs that we maybe should know, but don't. How much coinage does a shop have to accept legally? What IS the law re-waiting time on double yellows? Restaurant service charges....do we HAVE to pay? etc., etc. There must be millions of small - and large - niggles that we aren't totally certain about.......

You can spend many a night reading about the delights of Consumer Rights ... if you really really want to know all about that sort of thing.

And if you break em, ignorance isn't a defence! Be afraid, be very afraid.

I can answer the Double Yellow lines one, you CANNOT stop on a Double Yellow line at all, simple as that.

1 down, millions to go.

Anything above 20p (or is it 25p) in 1p and 2p coins does not have to be accepted. Service charges in restaurants are at the customers discretion.

I think you need the PerhapsBank, Gef.....or is it the MaybeBank?
