Vendors saying they don't service your venue.

So have yall ever have any vendor tell you no to a service for no reason I'm just not understanding? OK so I'm looking for a vendor to set up beach ceremony decor and I have one vendor say he doesn't service that resort implying my venue, so I asked don't he do ceremonies from pensacola to destin my venue is located in Fort walton. So he said yes he do John Beasley beach but they don't do resorts, but shouldn't he said that earlier not we do do that resort implying that he does other resorts but not mine? So it will be set up in front of the resort on the beach which I have permission for I just don't understand why can't they do it? At least lie and say your booked on that day which it's a Sunday I just am not understanding. Now considering I'm looking for someone else I'm just trying to figure out have anyone ever experienced this while planning? I just wish he gave me an answer that makes sense makes me think he isn't legal or something.
