I was just minding my own business, enjoying the sunshine without anyone else around for hundreds of metres. Out of nowhere, four or five dogs are suddenly galloping at me at a million miles an hour. One of them helps himself to my bag, opens up the tinfoil inside with his teeth, and within thirty seconds has devoured my entire packed lunch. The owner saunters up, says "Sorry, mate, sorry about that", and then wanders off as if it's no big deal. I know there's not much more he could have done, but it doesn't seem good enough when you've just found out you're going to go hungry for the next four hours.
