What a wonderful story
Cash remains king.
Yeah I was there, paying for stuff was a real shambles. In days gone by Glasto would have had loads of cash machines scattered about the festival site but I saw very few of those this year, presumably because they expected nobody to need cash.
Wasn't just bars, food stalls as well were constantly changing their minds on whether they could take card payments or not.
I am not sure it was wifi problems like that story claims, all the payment terminals I saw were 4G ones i.e. mobile data not wifi. And anybody who is a Glasto regular knows that the phone signal dies with that many people on site. To be fair it was very good this year if you were on EE (who are the festival mobile provider and put a load of temporary masts and capacity in) but I also had O2 and Three sims with me and they were absolutely useless.
The trouble with cashless is it all requires live connections as it's all real time transactions now. They need to roll things back to how it was a few years ago and you could take credit card payments offline and reconcile them later on when a connection is available. Yes there will be the odd person then able to get away with using a stolen or blocked card but it's a few beers FFS, not truck loads of gold bullion that they are getting away with.
