Looks like the WCC have decided to round up some more money in these cash-strapped times, they've started ticketing scooters etc. that are parked in the little "in-between" places at the end of car-park lines. A workmate has been parking in the same place for 3 years and got a warning last week (which he ignore to his detriment) and a ticket yesterday. I've also noticed somewhat more parkwise people wandering around recently than normal.
Interestingly though, the ticket was for parking on broken yellow lines despite the fact that most of the "legitimate" scooter parks in the area have broken yellow lines going through them.
Just in case, fair warning :)
