… But what got us was a tiny blurb, repeated in excruciating, expanded detail on the back [of the menu], about the expensive new septic system the restaurant had installed. Average restaurant effluent, they told us, was in the range of 150-300 parts per million, but this whiz-bang new system had dropped theirs down to 18 PPM and the effluent appeared clear if you looked at in a glass. All this right there in the menu, so as you were anticipating your meal you got to ponder the benefits of bio-activated septic systems and restaurant grease-trap effluent. [emphasis in original]
