At a local weekend market I visited recently there was a cheese stall and after a sampling I liked 2 of the cheeses so decided to treat myself as I hadn’t been near a specialist cheese outlet for some time. I saw the price of $19.95 on the cheese and you know I assumed it was per kg. The owner did say that it was 100g and yes I agreed and he cut me off a 100g slice from the block. I asked for a similar amount on the second cheese and that ended up being a chunk. It was at about that point I realised that the $19.95 price was per 100 grams. There was no way I could back out of the sale at that point as he had cut me off 2 pieces of cheese.
This is what you get for $36 (the plate is a small bread and butter plate btw)

I took multiple pics of the cheese to show the sizes because no matter which way you looked at them the pieces were small.
So this cheese worked out at $199.50 per kg.
This is the most expensive cheese I have ever bought or tasted for that matter.
