As the adage goes, you learn something new every day. Well, today I learned never to select pick'n'mix sweets from any container that's low down enough to be within a child's reach, after witnessing a two unsupervised children using their fingers to sample the wares, and putting back anything they didn't quite like the taste of. There was a time when I'd have berated them, but it's just too much of a risk these days to get involved. After a few moments their mother called them and went running off to her. I did at least inform a shop assistant that the goods had been tampered with, although I got the impression it was pretty much an everyday occurrence. So, you have been warned... What did you learn today?
