3 mile final for rwy 08 Juneau. Tower tells AK AL hold short. I flair and land, on my roll out AK 337 tells tower they are cleared to DA, DADA, DADA, IFR clearance. Well by then I'm off at Charlie intersection waiting past the hold short line for instructions. As soon as AK AL stops talking tower says 60R contact ground. I must say I have never heard an aircraft tell the tower we are cleared to..... I've always heard ground give the IFR traffic their clearance. Is this normal???
