Rudy Giuliani's impromptu Philly news conference at the Four Seasons -- the landscaping company, not the hotel -- gave an adjacent sex shop a raw deal ... and it's none too pleased.
An employee named Jacob at Fantasy Island Book Store -- an adult entertainment shop a couple of buildings over from Four Seasons -- tells TMZ ... Giuliani's Saturday event cost him and his partners some good cash.
He says they opened at 9 AM and by 10:30 AM, their parking lot was swarmed by Giuliani and his posse ... plus all the media/security tagging along to see what he was going to say about President Trump and the election.
With all the hubbub and cameras, Jacob says customers were spooked and couldn't get to Fantasy Island's front door.
He says they didn't get any warning about Rudy's plans, and it sounds like Four Seasons wasn't given notice either ... although it's reaped some benefit, selling out merchandise after becoming Giuliani's backdrop.
No such luck for Fantasy Island.
Jacob says all they got was a flood of phone calls from reporters asking if Giuliani swung by the adult store. That's a "no" ... BTW.
He adds ... a check from Giuliani for a few hundred bucks would make things right. Let's just hope he's not holding his breath for that.
