Narrative:

Clearing runway at taxiway east sna, I looked right and didn't see any aircraft. Proceeded to go back inside cockpit to perform after landing checks and contact ground for taxi instructions. We were cleared to gate. Pilot of other aircraft involved came up on ground and was irate that we had cut him off. I made a query with ground asking the controller if we had cut another aircraft off. Controller stated that there was an aircraft back there. Supplemental information from acn 302026: after landing runway 19R at sna, I exited at taxiway east. I apparently did not see a little aircraft. The tower supervisor said he had to stop for me.
