Recently I posed this question:
I want to express at the beginning of the lesson that I hope that all my listeners will enjoy my speech. Can I use the causative structure? I hope I will have you enjoying this lecture.
The answer was as follows. My sentence is allegedly inappropriate because in the case "you describe, you cannot make the listeners enjoy the speech, so you can't use the causative form above". Why is it so? I think that if I am a good speaker, I can make the listeners enjoy my speech.
In addition, in Oxford Dictionary I came across this sentence: If you play your radio on beach, you'll have everyone complaining. – I am not able to find out the difference between my sentence (I hope I will have you enjoying this lecture) and the one from OD.
