Nine cups of coffee would be about the average amount of brew one would consume during overnight surveillance operations...which we did a lot before we/SERT would hit a house. It was our lifeline to staying frosty while working Title III wiretaps, deciphering code words, drop-offs, nicknames, etc. In fact, as TFOs we would put our order in at the beginning of the shift to make sure we had a steady supply. Since retiring, I still find myself sipping on multiple cups on the road to whatever states I am heading to to chase birds. I like the flavored coffee so don't judge with a bit of creamer.
