When we did a trip to Jamaica (Bloody Bay) we had heard about some breweries that were off the reservation, and asked the resort bar tender (main lobby) how to get there for some samples and a tour. He strongly recommended that as pasty white americans we don't venture to that part of the island. It's not like something would happen to us, as tourism is such a huge part of the country's revenue and they wouldn't risk that drying up, but was still suggested we don't. The tender said he had family in the area of the breweries and would have them get us some, just come back to the bar the next day. Asked him how much to cover everything, and he said $20. We all pitched in and gave him about $200 for his effort, his family's effort, and for the beer. His eyes damn near exploded.
Next day we come to see him and he walks us behind the bar. Two HUGE coolers filled with all kinds of local beers. He tried to give us back $100 saying we gave him too much. We wouldn't have it, keep the extra and spread it around to whomever you see should get some. The service they provided during our stay was outstanding.
He put our beers in a separate refrigerator and gave us a second wristband of a different color. Then put that same wristband on the fridge. Told us just come and get what we want, when we wanted it, just show the wristband so they knew it was ours.
Their appreciation of our generosity was overwhelming. We were there for a week, so made sure housekeeping got a nice chunk too. I was in my own room and gave my person a $50 (this was 2012). When I came back I had two really nice hotel towels, plush robes, and slippers sitting on my suitcase. Went to give her more $$$ and she refused.
She was making up the room as I departed for the lobby to catch the bus back to the airport. I shoved another $40 under the door as I scurried away
