So my take from this thread is that PNW boaters don't typically tip, because there are seldom line handlers there to handle lines, because boaters in the PNW know how handle their vessels when docking . . .
While boaters on the East Coast don't know how to dock, frequently require line handlers to manhandle their boats in to the dock because even with multiple thrusters, twin engines, 15 satellite dishes, 5 GPS, and multiple steering stations, they can't seem to lay her alongside the moorings . . . . is that about it?
All kidding aside (and yes, the above was tongue in cheek) the only time we've tipped here in the PNW, and up to Alaska, was the first time we fueled our aft tanks to the top . . . and they were 200 gallons smaller, each, than we had been led to expect . . . . which MAY have resulted in an un-permitted discharge of a small quantity of diesel fuel . . . which the fuel attendant MAY have helped us to clean up . . . provided there was actually a spill that is . . .
Anyway, after settling up with the office on the fuel bill, I found the fuel dock guy, shook his hand, and a $50.00 bill may have changed hands. He was appreciative.
As stated in a previous post, in the PNW, the only time anyone has ever helped us tie up, it was fellow boaters on the dock, none of which expected a tip. I often offer to help people with lines, but I say to them, tell me exactly what you want me to do!
I've had people who, while well intentioned, felt that any dock line they handle has to immediately be cleated off TIGHT to the closest available cleat . . . regardless of what the boat is doing . . .
