Honesty

I was curious if the villager from whom I buy grain is honest. I had impression he wasn’t so I used my scales to weigh grain which should weigh 25kg per each bag. Well, in each bag there was only 23 kg. I bought from him 5 bags, so I lost 2kg x 5 = 10kg of grain. 

I also weighed potato bag and this one was okay. I bought potato bag in a village shop.
