I live in a low crime area. I know I live in a low crime area because I went into our local convenience store today and it was empty. Not empty of stock, just empty of staff.
I did my shopping, shouted for a cashier, shouted again, waited around for a while, and finally the cashier popped his head round the front door (he'd gone out for a walk in the sunshine) and asked if I'd found everything ok...
Nice.
