In Fear and Loathing in Las Vegas, Raoul Duke and his attorney, Dr. Gonzo, had 600 Neutrogena transparent soap bars.
I haven't been able to find an answer as to what their intended use was or why they would have so much.
Raoul Duke states that Dr. Gonzo had worked out a deal with some maids at a hotel they were staying in to have the stuff delivered to them in mass quantities.
When Raoul Duke is pulled over by a state trooper, the trooper asks about the soap and Duke says
I like to stay clean
to which the officer answers
I don't think so.
This implies that for some reason the soap is suspicious to the trooper.
So my question is, why is the soap significant?
