A cunning plan

The manufacturers of the washing-up liquid that is used in our house have devised a sneaky way to increase their sales - and presumably therefore their profits. They have not reduced the quantity of liquid in the bottles (at least, as far as I am aware), nor have they increased the price. They increased the size of the hole the liquid squirts from (OK - from which the liquid squirts - I've read yesterday's blog on Rants & Musings). It's only a very little bit bigger, but the result is that a gentle squeeze on the bottle ejects almost 50% more liquid than before. Even when I try very hard, I get about a third as much again. So, a bottle that would last say, four weeks, now lasts only three. Crafty, eh?
