It's Air Taxi or Ground Taxi on the ATC clearances - the difference between the two should be obvious and a skidded helicopter can only Air Taxi.
Most helicopter pilots understand exactly how FW operate so why do FW pilots not know about how RW operate?
I suggest you go and have a chat with ATC regarding heli ops at your airfield.
FW and RW pilots should fully understand the effect of downwash from a RW that can cause issues with light FW and plan their route accordingly.
RW will Air Taxi at anything between 5 and 20 ft perhaps higher if vacating from an approach to the runway - twin engine d helos will often taxi higher than singles.
Double barrel - you should have mentioned the potential hazard to ATC either at the time of by phone afterwards.
