One of the detailed changes, according to BBC News, is that bus passes cannot be used on services where over 50% of the seats can be booked. A spokesperson for the Department for Transport said this would "clarify" the scheme - no, really, she did. I can picture the scene down at Bristol Bus Station:
"Scuse I Drive, is this bus bookable for more than 50% of seats?".
"Oh ahh, this is a 357 which is a 55% bookable bus. You'll be looking for a 327 which is only 35%".
"Cheers Drive, when do the 327s go?".
"Tuesdays. Cept when there's an R in the month".
