borgata shufflers not accurately counting cards

[Chuck Norris]

dealer deals out a hand, sb notices he only has one card. dealer assumes he made a mistake, misdeal. and it so happens his down is over, and he instructs next dealer to count the deck to be sure. next dealer puts the deck in the shufflemaster, shufflemaster says all 52 are there.
we use the deck, the next time the deck goes through, it comes up 52 again. the third time through, it says 51, and we check under the rail (nobody checked earlier because the rail appeared tight and unlikely a card could get under) and theres card #52.
next day, same table, dealer is taking cards out of the machine, and some cards spill a little. it appeared to me that a card fell onto the other deck that the dealer loaded into the machine. i tell him, but he says no (the colors are extremely similar for some reason), they were ok. he deals the hand, whatever. machine says 52 cards for the other deck. he takes out the deck and spreads it to check the backs, and theres a card from the other deck in there.

so, at best, the machines (at least this one), are unreliable. shift said they had one other similar complaint about a different machine.
