nothing - I wouldn't know who to give it to!
We have several mail carriers, so I don't even know who my regular carrier is supposed to be. I think it is the one who does his overtime first & then does his route - which means I am lucky to get my mail before 6pm!!
Trash guys - there are 4 different trucks that come by (recycling, trash, yard & large household appliances) - they all come by at different times. I can't stand outside all day waiting for them so I can hand deliver the envelopes. With my luck, if I put them on top of the trash - they would think they are part of the garbage & just dumped.
Newspaper - I have no clue who the carrier is. We get the paper, but we never know where in our yard it will be. Since the last time I called to complain, the paper has usually been in the driveway. But, it seems that more times than not, the paper is so far underneath the car, we have to move the car to get to the paper. And the carrier deserves a tip why?? When I first subscribed to the paper (& the neighborhood kids had the route), it was put between the screen door & the house door. Dry, readable & easy to find. The kids always got great tips. Now some adult comes by & it is a whole different story. Last year around Christmas the paper carrier left a card with a note you can mail gift to ...& left the address...

Sorry, you want your tip - search the yard & maybe I'll leave it under the car or maybe I will wait until a really rainy day & just leave it in the driveway with out a plastic bag.....
