Sometimes you will miss a few cards while counting at the black jack table.

For example: Say you are sitting at third base looking toward first base and the seat next to it. The black jack player busts, throws the cards down, and the dealer sweeps them up with a flourish and you don't see all the cards. You can figure them out by deduction.

For example: The black jack dealer shows a pat up-card of 8. You then assume that the player at first base had a busting hand since he or she had to hit to be a contender against the black jack dealer's possible hard 18. You can presume that the player ended up with one small card and two big cards. Add it that way to your running count and go on from there.
