Amazon Go and the Future
I wish there was a mention that 5 people can buy the same milk and all can each pay a different price (and none know what the other paid either)I always thought it would be something to charge a wealthy person more since they can afford it.  With GO franchise i could charge $20 for milk to the teacher pensioner backed by my tax dollars; $0.50 to the poor mother of 3 kids, and $10k to jeff bezos. Then I could stop subsidising farmers.Of course my points are extreme but we never had a way to charge different people this easily
