There is a University in every corner of London. Mathematically, we can have more than four corners in any shape or polygon. But, what if there is a University in every corner? What if there are 12 corners in the polygon? You will have to be the smartest people in the world with all of these schools but your economy belies this notion. So, then I went to Aldi 's and I saw a gate at the front door and a bar code reader; something about you need an app to get in the shop. But, I left my phone at my desk at work during lunch. So.....so...well..so I looked around and saw a Walmart and went to Walmart that did not require any bar code to get in. I didn't really have time to get back to my desk and download an app to get in to Aldi to get my three green apples for lunch; and what does the app prove? It proves Nothing except that I have a phone. But, if the supermarket industry is based on convenience shopping, it's not convenient or conducive to the chain to delay the customer in giving the one dollar or one pound he intends to spend. It's not convenient. Anybody can get a phone. He will go next door. In fact, it is impedance and gimmicky. The supermarket should just want the money and for you to get in and spend it quickly. We left our phone in the vehicles or at home when I want jogging. It is an idiot who would do this. It's a 30 second decision as to where you shop. It takes you three seconds to walk away.
