I hate it when it's a result of just bad parking. But when the car park is fairly empty, parking across 2 spaces or in the Parent and Child parking is the only way to ensure that you don't get Zafira man parking next to you.
Even then you aint safe because Zafira man cant see properly, its all part of his condition, so now hes in the parent parking slot next to you, but hes missed his lines and still managed to park within striking distance of your door.
I tell you its all part of the patience trying urban crime environment we live in, there is only one answer, you buy a 300 quid Fiat Panda or something to go shopping in, or failing that a Zafira and join the growing ranks of Zafira man yourself.
