If you're trying to get a west bound train from Platform 3 during evening rush hour, don't try and get on via the first two doors as everyone else does and it gets too crowded. Move down the train.
Don't park in the parking right at the entrance of the station. A blond girl or her colleague usually standing in front of Holland & Barrett will take a photo of your plate and send you a nice fine.
if you get a fine for parking outside, don't pay it, it's unenforceable. you will get 4 threatening letters and they leave you alone. they also can't affect your credit rating without going to court.
