Logic

The other day I was in the market and I wanted to buy tomatoes. There was a pile of 10 tomatoes that cost 10 meticals. I had 9 meticals in change, or a 50 metical bill. The vendor didn’t have change. The logical solution that appeared to me was for him to take away one of the ten tomatoes, and let me pay 9 meticals for 9 tomatoes. When I suggested this he laughed and was like, “What, if you can buy 10 tomatoes for 10 mets you think you can just buy 9 tomatoes for 9 mets?” Well I thought it seemed like a logical idea, but apparently not.
