My rationale for choosing to be blatant (by giving each customer a signed, home-made, holiday card bearing my name and business address) was that although many people provide a small regular electronic tip when they pay their e-bill, a significant portion of newspaper readers are older, don't use the internet, pay with a check, and prefer tangible gifts over money.
The results have been positive. Dozens of gifts...cookies, cash, checks, and gift cards on porches, taped inside tubes, and in the mail.
This is about one gift. Not the most expensive (by more than half) and not the most elaborate (hard to beat a huge spot-lit crinkle wrapped can of ginger snaps for that)...an unsigned gift card without a return address; only marked from "a customer".
last year my new job has cut into sleeping, creating, reading, watching films and drinking at bars. I disc golfed as much as I club golfed. The move to a smaller place (house to apartment) took two months. Vacationing was limited to camping only. The hot tub was sold (as was my 5th wheel camper). Gaming increased thanks especially to Bethesda and Rockstar games.
