I was doing a short flight back and forth (practicing landings) and was instructed to "Maintain 300KTS or greater) @ 6,700 Feet. I replied Unable and was instructed again to do so. After being told to comply I finally increased my speed to 300KTS and had a speed violation and dropped back down to 220kts and was asked to state intentions again. I finally left, thinking this ATC was going to ghost me.
I was flying into St. Marteen FWIW. I did not take a screen shot of the incident and do not have the ATC name. Can one of the ATC members on here advise me on a better way to handle this? Or reply? Training Server 1
