Refueller induced damage
Every paint chip/ding (but one - done by engineering) on my aircraft is a direct consequence of refuelling. I cringe when they climb the ladder with their heavy boots and steel toecaps millimetres from my fuselage and splash fuel all over my paintwork.
Best to refuel it yourself and keep the fuel monkey off the ladder.
I may sound obsessional here but put another way how would they like having their prized car of commensurate value treated the same way?
Although no use for longer trips a bowser at home helps to minimise the need for fuel uplift at airports and consequent damage or contamination acquired through refuelling. It also helps keep the cost down (by about 20%).
