Food court woes

I read an article recently about a lady who had photographed the aftermath of a family who had been eating in a foodcourt. She was irritated by the mess that had been left. I remember a couple of weeks ago I'd been with my family eating lunch and watched a family leave a horrendous mess behind them. Another family came behind them to take their table and had to clean the mess up before they sat down. The poor Dad had sauce drip down his jeans. And boy was I horrified. You know how everyone has pet hates? Well this and parking in parents with pram carparks is one of mine. The cleaners should not be paid to clean up after people who are perfectly able to walk their trays to the bin which is less than a metre away. End rant...
