John B gurgled happily, sounding much like they were
saying:

In the UK it is also conventional that you notify your bank if you
intend on travelling abroad.

It is? I've never done or heard of this, and nor have any of the other

I've never done or had a problem as a result of not doing so - but SWMBO
seems to think that they need to know. God knows why. Mind you, she's
with Barclays, so I really wouldn't put anything past them.
