It was a crazy sentence.  The prosecutor broke the offenses down into several different charges.  For example, because he moved employees into a backroom during the robbery he was charged with kidnapping.  There were a total of eight different sentences which had to be served consecutively.

Given that they all flowed out of the same event, he should have been sentenced concurrently.  I've never managed to figure out the basis for consecutive sentences, but all together it added up to 98 years.
