Cheese in this case. My favourite St Agur is now 125gm, previously 150gm. When I cut a bit off the end, I thought the wedge looked thinner....noooo, must be my imagination. Nope...it's smaller. And of course the price has gone up recently. :((
Common practice nowadays to reduce the quantity rather than increase the price in the hope that the customer doesn't notice. It's called 'shrinkflation'.
