I just can't resist to repeat here one of the "guerilla" tips (how to beat the airline's system" from early FlyerTalk-Times (last year):

How to double park next to another unloading car beat the traffic-warden when double-parking:

1) park just before the crosswalk (also for traffic-wardens it seems natural, that cars stop before crosswalks)

2) than you and your driver leave the car: your driver unloads the luggage and you move in front of the car peering intently at the pavement

3) the driver complains to the traffic-warden: "that person is blocking my way"

4) you explain to the warden that you just lost your contact lenses

5) when your driver has finished his unloading-job, by miracle you have found the lenses.
