The chocolate o'clock box contains 'Heroes' at the moment. Back in the olden days they were mini chocolate bars. These days they are more like mini chocolate bites.
When I first discovered how small the contents of the wrappings were I began to feel a bit miffed, but after a couple of second's thought I find I'm not that bothered. It is a ridiculously expensive way of buying chocolate, to be sure, but this way the amount of sugar and fat I consume (always provided I take only one piece) is kept to a minimum. So, all things considered, it's for the best.
