En route home last night, an (admittedly chav) couple were standing at outside the Tube station munching through a bag of fries. They finished them and, despite a bin being 10 feet away, tossed the bag into the gutter (which we'd watched a guy sweep clean about 5 minutes beforehand). The bloke then finished licking off the fork and tossed that to join the greasy paper bag. Litter bugs are one thing that really irritate me particularly when there are lots of bins around. So what turns you into a Grumpy Old (Wo)Man?
