In contrast, the local PC shop used to run it's Internet Cafe machines pretty well open and over many many years and rarely had any issues.
'Most people' just wanted to do what they needed to do, like get / print some airline tickets (because they didn't have a working printer at home) or kids doing homework or bidding on stuff on eBay as they didn't have a smart phone (or did but didn't have any data credit on it).
