Lot of old farts in here who hate change ;)
On a serious note, if its for a small shop (pint of milk, loaf of bread or sumat) I use them every time. Takes seconds and is notably quicker than having to queue for some shop assistant to do exactly what you can do yourself, but with less faff and questions.
I honestly don't get why so many find them confusing. They're pretty straight-forward. I admit they're annoying when the lights go off, but it still ends up quicker than queuing for an assistant in most shops, as those queues are usually full of older people who take far too much time. Or some cashier who is genuinely dreadful and takes forever to do the simplest of tasks. It's also genuinely annoying being stood behind queues of people slowly packing bags while chatting shite to some cashier. It takes about 3 or 4 times longer.
I get the job thing of course, but yeah... we all do things that cost people jobs. None of us were particularly arsed when the internet killed off yellow pages for example. Most of us aren't too arsed that most local shopping centres have been killed off, as we've got Amazon accounts. It's sad, but that's life innit.
