It's quite unusual to get a £2 coin in manual change, but London
Underground ticket machines churn them out.

Happens all the time in Lidl, Aldi, 99p stores - they seem to give
change on a "minimum number of coins" basis so the same for 20p and 10p

Since my launderette only takes £1 coins I occasionally have to ask for
4 x £1 rather than 2 x £2
