I see hundreds of tweets by @amazon that reply to people complaining how deliveries miss the dates that amazon dot com promised but then amazon dot com probably delivers so many packages every day that I think it is a bit of column A and a bit of column B here.

This makes the same classic mistake about social media about social media that my boomer dad makes.

100s people a day or even an hour is not a lot of people. It might feel like it is because in person it is but for the over 20 million packages they deliver daily it is rounding error.
