I'll probably need an airport tour to answer this to my satisfaction, but I
thought it merited a discussion here anyway.

It seems pretty standard that, after an airplane is refueled, you wait 10-15
minutes and resample the fuel to check for contaminants (water). I recently
witnessed a situation where the fuel was checked during preflight, but not
after refueling. The reason given was that at this particular airport, the
fuel supply is replenished/recycled daily, if not more, and so there isn't
time for water, or perhaps *enough* water, to collect in the storage tanks
and end up in an aircraft's fuel tanks.

It could. The truck's tank should be sampled and checked for water
just like the airplane though. It is a good idea to check the fuel
after fueling (I usually skip it during the pre-flight if I'm going to
go get fuel).
