Yes, pilot negligence, because he had signed the fuel receipt stating clearly "Jet-A".

Neither the first nor last time, unfortunately.
This is one of the well known ambiguities which can lead to misfueling, for that reason in training that I have been involved the issue is highlighted and then fuelling operators are told to ignore such wording.
The only wording to be concerned with is clear, unambiguous grade placard/decal situated at the fuelling orifice.
