They are often referred to as "bog roll" tickets on here.Whenever I have bought tickets from booking offices, they have always been card tickets with orange top and bottom stripes on the face, rounded corners and a black stripe across the reverse. I have never been issued with a paper ticket. What areas of Britain issue paper tickets? I am 77 years of age.
However "card" tickets are also generally referred to as paper by everyone too.
If paper or "card" the same points apply.
