I agree with all of the above. Don't sweat it.
In addition to the multiple counts, learn to balance your drawer throughout the work day. If you balanced at 11:00, 2:00, 4:00 and you still come up short, you may be able to find it in the work that occurred between 4:00 and closing.
Of course this all depends on how busy you are. If you have down time and worry about not balancing, balance throughout the day.
