Was I suppose to tip the captain of a cruiseship for getting is to and from the ports safely? Again, where do we draw the line, rewarding people for simply doing their job?
The welder is here, on the Spree on a Saturday after getting on the ferry at 6 AM and riding down from where he lives. He will go home tonight (if he finishes) and arrive about 10:30 PM. I will pay his hourly wage for 16 hours for 6 hours worth of welding. I will pay his ferry bill. I will buy his lunch and dinner. I will tip him handsomely, because I was in a bind, and he gave up his day off with his GF to help me out.
He's just doing his job.
Yesterday, a boat came in the yard. He had bent a wheel and was afraid he had cracked his shaft. I happen to have a NDT tester, so I magnafluxed his shaft in the boat for him. No crack. Although it was not my job, I happened to have time (while waiting on the welder) and the tool for the job. He was effusive in his thanks, and I got a bunch of lobster tails for it.
Tipping shows appreciation for making your experience special, or going above and beyond the call of duty. Yes, you can say that liveaboard staff live the dream, or they knew what they were getting in to when they signed up, but in reality, they are making your experience from just going diving into a special occasion. Take the lousy pay out of the equation and look at the situation another way. It's a way to say a heartfelt thank you. There are other ways to accomplish the same purpose, a really nice review of an operation on a big chatboard or to Undercurrent is one such way. Leaving behind some treats that are hard to find in whatever rat-infested country your boat happens to dock in is another. Those methods of showing appreciation are just as good and sometimes better because they come from the heart, but a lot of North Americans don't know how to speak from the heart, nor will they make the time to write a thank you card except to Grandma for putting on a Christmas feast.
When we get a great review in a public place (Undercurrent, ScubaBoard, TripAdvisor) we all gather round to read it, and pat ourselves on the back for a job well done. That actually means more than a cash tip. Most won't do it because it takes effort, thought, and a little of yourself to do it.
I think it was Chug who reviewed the Spree after a one day trip to the Vandenberg in '99. That meant more to the crew than any amount of money in the tip jar ever could have.
