Narrative:

When receiving an IFR clearance from poc; I was given a clearance that included; 'runway 26L departure procedure; vectors to join...(rest of route)'.I looked through my electronic charts and procedure database in my garmin 400 and did not see a procedure listed. I; admittedly; did not ask for clarification prior to departure.after handoff from tower and radar contact with departure; I was asked why I was not in a left hand turn in accordance with the departure procedure. I admitted that I was not familiar with the procedure when asked and vectors were given. Although the controller did state that; 'he was not going to violate' me; he continued to question me on the radio and asked 'why' several times.I have two concerns with what occurred this morning. First and foremost; I should have looked at the airport notes and the odp(obstacle departure procedure). Completely; 100% my fault and a very strong lesson learned. My second concern is that; although I appreciate that the controller was trying to help me learn; as a single pilot flying in complex airspace trying to correct a bad situation; I would have preferred to discuss the situation with the controller off-line; after the situation had been corrected. I have definitely learned my lesson after this; and the only take away I would like to provide the national airspace system is; that although tolerance and guidance are hugely appreciated by pilots like me; the added stress of trying to answer 'why' and 'what were you thinking' questions is counter productive to correcting a possibly dangerous situation.again; I greatly appreciate the help and guidance I receive from ATC everyday; but wanted to submit an example of a case where the lesson could have been better absorbed with an after the fact discussion versus 'real-time.'

Title: Despite not understanding by which departure procedure he was cleared; the Pilot of an EA500 took off from POC and was confronted by an ATC Controller who clarified the procedure in a manner the reporter felt was unnecessarily brusque.
