What is Stella, alcohol? If so it doesn't surprise me, a 6 pack of beer at Bev Mo sells for $6 or so (thank you ajohn) at a night club it's $36 ($6 per beer hopefully including tip, for them to reach in the fridge,grab one, pop the top and hand it to you).
You never heard of Stella?? It's a beer. Has to be poured in a special glass. It was on tap so I figured it would be a better deal. Wrong!
By the way, not to brag, well maybe a little, I launch, fuel, recover and store solo a lot not because I want because I have to more often then not lately.
You would need to see my situation. I keep the boat in a slip, and the ramp is maybe 1/4 mile away. It's a single ramp for the marina with no courtesy dock and in a tight area. So someone else has to drive the trailer, otherwise by the time you slipped the boat, and ran back to the ramp to get the truck you could potentially lock up the ramp for a good 15 minutes. And, vice versa putting the boat in the water. It's just not convenient. I tried to do it once using a mountain bike, and that was a royal PITA. During the course of the summer I maybe will pull the boat out 1 time.
Tipping for gas on the water too me is like tipping when I buy meals to go. It depends on my perception of what services the service provider has rendered. If the gas attendant just takes my money and hits the on button or in the meals case just takes my order and hands me my food along with a bill including tip line then no tip. In the meals case if the order is order is right and ready when I get there I don't mind leaving a small tip, especially if I frequent the place often.
Related experiences: Years ago my friend and I were at a club/bar. He ordered a $3 drink and left a $1 tip. The waitress asked him why he only left $1 for a tip. He asked her for the bill he signed and promptly scratched the $1 tip off of it. I've also seen a lady do this when she had to return to the restaurant because they got her take out order wrong. In another instance, I was leaving a restaurant by coincidence with another patron, his waiter came out to the parking lot to confront him about stiffing him on the tip. Eventually waiter's manager came out, heard both sides of the story and fired the waiter on the spot.
My point is that is all about expectations, I have to work for my money so I expect others to work for it as well which is not unreasonable at all too me.
