In a "past life" (earlier career) I managed the service department in a large audio/video retailer (before the now defunct 'superstores').
Our head car installer, who happened to be gay, had just completed a custom installation on a vintage VW bus for a couple of young ladies, regular customers, that we knew were lesbians. Half an hour later they returned complaining that the stereo was "buzzing".
We went out, one of the girls was sitting in the van with the system already on, and he ran it through it's paces. It sounded great. There was no "buzz"...or at least certainly not coming from the speakers. However, when he turned it off, we could distinctly hear a "buzz" coming from the dash. Perplexed, we cycled the stereo off and on, looked under the dash, listened closely at each of the speakers, and couldn't hear it coming from the system.
Finally, he opened the glove box, and there it was. A classic 6-8" long vibrator, in all of it's pink glory, merrily buzzing away. I don't know who turned redder, him or the girls, but we all ended up laughing till our breath was taken away. I had feared they would stop shopping with us but, thankfully, they continued to be our customers, without embarrassment, and without shame, for many years to come.
Two hot stories, would love to hear more! I don't have much of anything to compare but I love watching a couple of females shopping in the adult stores and listening in on their convos!
