The more sinister side of the Chatty Hairdresser. Loose Lips sink ships — and where will you find looser lips than in the midst of centers of socialization and self-indulgence such as beauty parlors, barber shops, nail salons or massage parlors? People assume that the help is being paid for their discretion. But maybe they're only pretending to be a sympathetic ear about that project you're working on at work. Or maybe that fellow customer is just pretending to be waiting for the next empty styling chair as cover for hours of listening. Failing that, trapping some VIP (or their significant other or faithful subordinate) under the hairdryer or at the shampoo basin gives one an excellent opportunity to rifle through their purses or coat pockets...
In more fantastic settings, out-and-out mind-reading might be involved, making spas particularly useful for psychics who need proximity or touch in order to read minds. For more aggressive intelligence operatives, this may lead to a Bathhouse Blitz or Sauna of Death.
