Plenty of people work hard, not just postal delivery workers. 🙄 You are making it sound like they walk around the planet everyday in hurricanes, and 6 feet of snow, and are the hardest done by workers in the world. And they are out til 8am til 3pm or 4pm? Actual wow! Many people are out/at work waaaay more hours than that.
And as some people have already said, some days they don't get any post in their village or area. We (rural village, 3.5 miles from the little town) only get it on 3 days of the week. (Monday, Wednesday, and Friday only.) So they're not always out every day, and they do pick up the post from the postbox sometimes up to 20 minutes late, as long as they get it back to the sorting office for for when it closes, it doesn't matter. (Also, the postie who delivers our mail, in the morning, is never the same one who picks up the post at 4pm from our village postbox.. And that is only collected on Monday. Wednesday, and Friday too!)
And yes, of course they're going to clock up some steps, they're a flippin' postie! 🙄
We get it, you (or your husband, or one of your close relatives) is a postal delivery worker. YES they do a good job, but so do millions of others. They don't deserve a tip any more than anyone else.
