I was in the queue for the checkout in M&S yesterday and someone's card was declined in front of me and I suddenly realised I've been seeing it more and more often recently. One notable example was in Morrison's where the self checkout loudly announced "sorry, your card has been declined" which I thought was a bit embarrassing for the guy in question. I mean, surely it could be a lower volume or something? I'm going to mute the self-checkout every time I use it now.
Anyone else noticed this?
