Narrative: During boarding procedures a passenger was advised of the mask wearing requirements; nose/face. Flight Attendant (FA) advised passenger nose exposure to FA B who also had to re-advise passenger.  Passenger appeared disgruntled about requiring nose coverage and Gate Agent advised she also had words with passenger with same response. FA B advised Captain of passenger's position against compliance.  Prior to door closure the Gate Agent was present in case passenger removal was necessary.An announcement was then made saying 'non-compliance passengers were noticed and removal option would be used for non-compliance.' Passengers were advised they had an agreement at ticket purchase this had been clear this was not an optional requirement for flight.Using this method passenger realized this wasn't a joke and removal would occur.  Captain advised FA B to do walk through for compliance and removal before door closer option.  This passenger had been advised over 3 times by 3 different individuals with non-compliance results and now aware airlines was serious about compliance.Entire plane was compliant during walking through and continued flight. During entire flight passenger continued to pull mask off nose and appeared disgruntled. Passengers around passenger kept saying 'FA caught you again each time' so passenger then laughed like it was a game.  We are to 'inform' at this point; which continued at every walk through; 'not enforce .' This was a constant occurrence during flight.After arriving and during departure this non-compliant passenger stopped and made rude remarks to FA A.  FA B went to Gate Agent during cleaning to advice of this passenger's attitude and non-compliance so Gate Agent could make a note for future travel. This passenger felt he was not going to wear mask as required. FA B advised gate agent row and seat area and agent opened up the location and verified passenger's information.  Due to constant resistance FA felt safer not to confront passenger directly. During 3 points this party was given clear instructions on mask covering requirements and possible travel denial.  They continued during every stage with 4 different advisory points pre-board at gate; boarding (flight attendants);  flight introduction (Captain's announcement) and inflight (flight attendants). With actions [during] deplaning this passenger let FA A know that they were above this rule.
