Quoted from PW79:I overtip,
I also overtip, the standard percentage for not so good service, closer to 20% for good service.
edit- when my Tron came the other day, my house is on a hill, I pushed the box from the bottom as he pulled with his pallet dolly, and I gave some major push effort, he had an easy pull, then I got my 2 wheel dolly out as we cut it from the pallet and put right through my front door up 2 steps, I also didnt tip him....
