Airport
I landed Runway 19 in FRG; Farmingdale; NY. I turned left off the runway onto G3 and was instructed 'taxi Gulf cross Runway 14 to the FBO.' You enter the FBO's ramp utilizing G4 Taxiway. I taxied north on Taxiway G. When I entered the actual surface of Runway 14/32 I see a hold short line on the runway running north south and a red runway sign on either side saying 1/19. To taxi across Runway 14/32 and stay on Taxiway G you must cross this hold short line completely from east to west. I stopped the aircraft on Runway 14 and asked the Tower if I was cleared to cross Runway 19 to stay on Taxiway G. The Tower replied that the hold short line was not for me; it was for aircraft landing Runway 32 to hold short of 19. I understand his statement and if you look at the airport diagram you see the LAHSO depicted there.The LAHSO depiction and the actual painting of the lines on Runway 32 are in two different places. According to the airport diagram you would never cross the hold short line; while at the actual airport you cross over the Runway 1/19 hold short lines while taxiing north on Taxiway G. I proceeded to ask the Tower again if I can cross the 19 hold bars to continue north and now he became frustrated with me. Eventually we worked it out and I continued taxiing. This is extremely confusing and unsafe. The Tower kept stressing how those hold bars were for landing 32 short of 19. I understand that. What I don't understand is how a pilot would be expected to know that they don't need permission to cross these specific hold bars. A student pilot or someone with less experience is going to get told this and one day this is going to lead to a serious runway incursion there or somewhere else. One of two things needs to happen: The Tower needs to acknowledge those hold bars and clear aircraft to hold short of them or cross them.  Or; the hold bars need to be repainted just west of Taxiway G so they will remain off your side the entire taxi. You cannot train pilots that some hold bars are ok to cross without permission while others are not.
Pilot reports of confusion while taxiing about hold short bars that he isn't sure if he should cross or not.
