Saw a couple of 9-12 year olds who had a lemonade stand, $1.50 and took Square payments. They had an iPad setup. Interesting to see, but a credit card lemonade stand. What next? Interesting to see a POS system pretty much used at a lemonade stand now. Just a funny Apple related sight I'd like to share. I guess due to the nature of taking cards, that lemonade was expensive.
