Typically, these creeps are making up a lot of details. I actually tracked back the original story, and even in the Russian source they link it says:
"In return, we get a splendid evening and a cool city tour from a pikabushnitsa and her boyfriend. Anya, Seryozha, thank you so much, it was great! I will definitely repeat this trip to Maslenitsa" , - said the user."
So no, they didn't just slam the door in his face or whatever.
There's also photos of a whole convoy of people making the trip, And from the original guy's other posts, it seems what really happened was a guy on a research assignment to the island was making a work-related trip with coworkers to the island, and arranged to see friends on the trip and brought them a treat.
