Not today, but last Friday. Wanted to exchange an old ten pound note, for a new plastic one. Popped into the first bank I came across, which was Lloyds. Joined the queue at the only manned counter, only to be told, I needed to be a Lloyds' customer, as I needed a bank card for this 'transaction!'
Went to my own bank (NatWest), where the 'greeter' exchanged it for me, circumventing the queues, and without asking any questions.
