Statistics

I was reading random stuff on the Internet one day and passed this trivial article.
I didn't think anything of it really - though I do try and choose the shortest line even if the people have a full cart - until I was in line at the market today.
For timing, it matters not how many or how few items a customer has in their cart if they forget their wallet in the car, send a kid out to get it, the kid doesn't come back right away, brings more items with them when they do get back and a discussion follows about which items they will actually be purchasing on this day.
Good thing I wasn't on a schedule.

This is me and it's the little things that matter.
