I believe that the hand would have to be played short one ante. I'm not in favor of the house making up the shortage. It could be considered a nice gesture by some but, once you start doing that, when do you stop. This is clearly the responsibility of the dealer. While the dealer is shuffling the cards , they should be calling for "antes please." Any dealer should be aware of the number of players at the table. By the time the shuffle is completed and the dealer has made a half cut onto the cut card, the correct number of antes should be gathered together by the dealer (using two hands). The cut should not be completed until all players have anted.
Once that happens at a table, everyone will be watching.
