When our local wailing wall had £5s and £10s it would always run out on
a Saturday lunch time. Now it has £10s and £20s it seems to be good
for the whole of the weekend.

Went into a cash machine inside a branch of Barclays today and upon
pressing the 'Any other amount' button was pleasantly surprised to see
at the bottom of the screen 'Notes available: £5 £10 £20.' Took out £75
in three denominations. I've never seen it before, anyway.
