Narrative: The airport had just gone below CAT 1 so we had briefed a CAT 2 approach. We were filed for the RNAV STAR. ATC gave us a heading to intercept the localizer approximately 25 miles out from the runway. That had shortened the arrival which has a large delaying 'S' turn. We had double dinged the cabin at 10;600 ft. ATC was controlling our speed and had us slower than we would normally be that far out on a better weather day. The approach and auto land went as expected. I had selected autobrakes to level 4 considering the weather.   We parked and finished our debriefing of the flight; we then opened the cockpit door. The Lead FA came in and said 'Captain; there is a passenger that wants to talk to you about the landing' and she started to leave. Desiring more information; I said 'wait; what does he want to know about the landing?'  She again repeated that the man wants to talk to the Captain about the landing and she left. I grabbed my flight bag and belongings and proceeded towards the exiting door (2L) to say good-bye to the passengers.  That exit door has a walk through galley; but the curtain was closed. A man had walked through that closed area and opened the curtain from the inside. When the curtain opened I first noticed broken glass on the floor. Then I observed the man who appeared to be upset. He asked me if I was the Captain and I answered yes I am. He said are you the one who landed the airplane? Because of his body language and his tone; I ask him to calm down and he replied to me 'you need to calm down'. I said I am the one who landed; (did not tell him it was an auto land). He claimed he got hit in the head with a galley cart that came down the aisle on landing.


Second narrative: On the descent; Captain followed SOP by alerting the flight attendants at 10;600 feet with the CABIN ALERT button (pushed twice.) We made a normal AUTOLAND approach and landing with AUTOBRAKES 4. After shutdown and completing Parking and Termination checklists; Captain was asked by a flight attendant to meet with a passenger about our landing. I observed a passenger walk over to speak with Captain; but could not see or hear the passenger since they met in a galley area near door 2L.


Synopsis: B777 Flight Crew reported that an unexpected autoland due to a change in weather; resulted in a shorter approach and insufficient time for Flight Attendants to secure carts; one of which struck a passenger.
