Now you see, I seem to have the opposite problem in my temporary Tesco delivery driver role...Every now and then I'll have to pull up across the driveway of the next house along. For some reason, it seems to happen annoyingly often that I'll park up, get out the van, and by the time I'm knocking on the customer's door, next door have decided that it's the best time to leave the house!
Along similar lines, if I'm delivering to the end of a cul-de-sac or dead end, I'll always turn the van around before doing the delivery, as, in the first few months, it seemed to happen, again with annoying regularity, that I'd pull up, get out the van, and mid way through the delivery someone would park in such a way that I then wouldn't be able to turn the van around!
