I am forced to say it again...now knowing you've been there 33 years. It is amazing to me that you are just now noticing this. I just retired with 32 years, and it was this way from day 1. I, as a newer driver would be forced to take stops off neighboring routes simply because those drivers were slooooow. It taught me real quick that there was only one reward for working quickly, more stops. That ended real quick. If you want to call me a sloth, so be it. At least I was a wise sloth that wasn't about to get treated like a doormat.
Nice pool btw. It's great to go home for lunch and take a swim. I did it every summer day for years! Now it's my full time job!
