We are on the free Aire at Roquetes with free EHU ... 2 minor inconveniences: at 0730 the workmen arrived to dig the cassette and fresh water supply up, and by 12 noon still has the services disabled (and our cassette runneth over, but not with joy ...), and at about 11:30, a German couple strolled onto our pitch and accused us using 2 x EHU, and demanded that we 'hand one over'.
A polite request may have persuaded me to offer a split of the supply, but the aggressive tone and repeated references to 'Ein Englander' led to a pointed response that there are 5 pitches for 4 EHU, so you will have to wait for someone to move' 3 times they came back with the demand ...
