Why I hate the bloody snow

Okay, so yesterday I was stranded at work. Every road from Hitchin to Letchworth was chocka with cars and my dad couldn't pick me up and it was a good 4 or 5 miles walk home. So rather than go straight home and face the freezing cold, I figured it would be better to duck inside the Hitchin Corn Exchange with some work acquaintances, for just one pint, y'know. One pint became five or six and then I announced that I was quite ready for the journey home, much to the protests of my workmates who even kindly offered to put me up for the night, which I declined cos I don't know them so well and I just wanted to go home.
So I start trudging (or staggering) past all the static cars, thinking "Hey it's not so bad, these guys are going to be here for ages and I'll be home in an hour or so." So I'm still quite tipsy and start chatting to people in their cars telling them to turn around cos it wasn't worth going on. I passed at least 9 cars that had skidded off the road and the whole place was a frosty warzone.
Halfway up an enormous hill between the two towns I got cut short and ducked into a bush to have a wee. Taking great care to perfect the anarchy symbol i had etched into the ground, I zip up my trousers and hear "You are charged with urinating in public, everything you say or think will be taken down and used against you in court". Yep. Despite the ensuing havoc all around me, the police thought it was justified to bollock me for having a wee in a bush in the countryside. I mean what the FUCK! I protested and told the officer I was walking back from work "I've been working for nearly five hours now sir, you don't see me urinating in public, do you?" was the smarmy reply. I'd started at 9am and it was now 9.30pm. A little more than 5 hours I think. I asked where else was I supposed to relieve myself? The answer "You could've gone a bit closer to the bush" I am standing IN the bush. Any closer and I would have slipped over and had my eye gouged out by thorns. "Or you could go over there (points to someone's front garden)". When I explained I wasn't willing to break into and piss in someone's private property, the copper replied "I would. Anyway, you'll either get a caution or a summons. Goodnight".

What a bastard. I arrived home at midnight, got 5 hours sleep and started walking back to work again. Am I being unreasonable or were there better things for the police to be getting on with on the snowiest day of the year when there were huge gridlock traffic jams, cars smashed into each other, people unable to get home and powercuts in many areas?
