Aircraft X was assigned Runway 1R via A-A1. I turned my attention to placing flight progress strips delivered by CD; when I heard Aircraft X say they turned and went F1-B. There were no other aircraft affected. I instructed the aircraft to continue B to the end; then A-A1.There is something about the complexity of B & A between E & F1 that just perplexes pilots. I am assuming that this is not a usual line crew; given the holiday; so there may be a lack of experience taxiing at SFO. With that said; they made a mistake and it could happen to anyone.
SFO Controller reported of a taxiing issue. Pilot was given taxi clearance A-A1. Pilot reported they taxied via F1-B. Controller told the pilot to continue via B to A1. Controller reported about complexity of B & A and E & F1 that pilots have problems with.
