This tour was booked on private basis still the clients were forced by your guide to be back to hotel by 1500/1530 hrs. due to which they had to miss all the shows (except 4 shows Dolphin, Sea lion, Monkey and stunt show).
When the clients requested the guide to allow more time so that they could enjoy rest of the shows, your guide clearly refused saying that his duty is only for 8 hours so he cannot be there till evening or else clients can manage the return transfer on their own.
Please advice as to why they were dropped at hotel around 15/1530 hrs when the arrival time in hotel is around 1800 hrs as the tour description on your online system. Below screenshot for your reference.
Guide or driver nobody was ready to listen to them.
