Well maybe I'm fortunate. My experience with being fuelled is ...
'G-XXXX to the pumps'
By the time I get there the pump crew (who are also the fire crew) are ready. I hop out and have a friendly chat with them while I see how much they put in, compared with my request (and, in future, what they put in).
Then a friendly thankyou, a shake of the wingtips, check of the fuel drains and off we go again.
I have assumed that water will very quickly separate from avgas and a shake of the wingtips will help it to migrate to the lowest part of the tanks.
I actually have no proof for either of these assumptions.
The fuellers here are people motivated by a desire to not use their rescue skills; I am motivated to treat them as responsible, decent people.
If I don't care about people, some day, someone important may not care about me.
