When my buddy and I were travelling to South Dakota each spring for prairie dogs shoots most of the little towns in west central SD didn't have chain restaurants just one little diner/bar with the same servers day after day, all day. We were easy to spot as not being "from around here" and due to the time of year the servers had a pretty good idea why we were in the area. My buddy and I usually ate breakfast and dinner in these little diners and always tipped the servers very heavily and said please/thank you. It didn't take long for that generosity and courtesy to be noticed. Usually within a day or two the servers were introducing us to other customers who had property with prairie dogs and in a few cases the locals dropped everything and escorted us to the fields.
After our first year out we started carrying some simple fencing tools, wire and splices with us to fix any fences or gates we found damaged. We also made sure to let the property owners know of any fencing problems we could not fix. As a thank you to the property owners we also carried with us a goody box of agency hats, belt buckles and coffee mugs to be left with the property owners before we left the property. It didn't take long before we had a pretty good list of ranches where we were welcome.
Those generous tips to the waitresses paid us dividends in getting excellent service on return visits, ample servings and were obviously appreciated. Paying respect, courtesy and simple gifts (tips) to the property owners also paid dividends for us for many years.
