If you wanted humor, my favorite way of serving someone was following them to the bathroom, act like I was doing my business, go to wash my hands, ideally your mark would wash their hands too if they saw someone else doing it, grab a paper towel for myself and and I would hand them their papers and tell them they were served.
Then I'd would bolt out of there like O.J.
But honestly, let the Sheriff do it, nothing gets their attention more than having a cop car pull in front of their office or home, stand on their doorstep, hand on the gun if they get stupid and serve them papers.
Its a real wake-up call to them that you mean business, its a real deer in the headlights look on your mark's face when that happens.
