Having used them in the 80's when I was going to football all over the country they are significantly better, and more plentiful that they were then. Some are still grim but provide a service to drivers. Some I'll happily take a break in and eat in and others I'll use purely use in case of a quick nature break and nothing else. Are they under invested? Are they victims of their own success in terms of being a captive market unless you leave a motorway and start searching for alternatives
