You're sick of everyone grabbing your parking space, each time you're slightly delayed. More than that you hate having to drive around to find a spot. They know it's yours, but somehow since there is nothing to mark it, they think it’s okay to feign ignorance. Well why not put up the Chelsea F.C. No Parking Sign, so that next time they park in your spot you can point to the sign and say no parking. You will win each time, until you run into another Chelsea fan, that is.
