Generation impatience

Usability News reports research by easyMoney that 18-29 year-olds in the UK neglect themselves because they're too impatient to wait for doctor, dentist or hairdresser appointments. Apparently queuing is a thing of the past and the blame for this is laid at the door of the instant access to services via the internet that this generation has enjoyed. I'm sceptical. Would this generation have been any different in pre-internet days? And is service access via the internet really so instant?
