If your dad is shopping for clothing, it is very probable that some of his clothes were set on fire, or that he had a pair of boxers finally disintegrate.
But you will not have to worry about spending much time browsing. Dad shops for clothes with the speed and singularity of focus of a NASCAR pit crew. He will walk in, wander somewhat until he finds the right section, purchase the first shirt/pants/probably-socks-let’s-be-honest-here-he-needs-more-socks that he finds, and be on his way.
