new cards

just played a mohegan sun today and got there when they were opening up new tables in high limit pit at shift change.they were bringing the cards in loose in plastic bags with a zip tie on the bag...the floor told dealer "count em,wash em,and shuffle them"...ive never seen this before and they counted them face down...they usually break open new decks check and count them face up for all to see wash em, shuffle and deal..does anyone know whats up?
