I have noticed that on the expert server, there are many rude controllers. Yes, it is the expert server and it is mandatory to obey ATC. But some controllers are very rude to pilots just enforcing their authority over us like barking orders rather than controlling respectfully.
For example, sometimes when you contact ATC, they dont even bother asking your approach plans or anything they just tell you what vectors to do. So I do that, and I say my approach/ask to descend on the STAR. They reply by telling you to follow instructions. There is literally a button that pops up saying unable, expect vectors. Instead of pressing that, the controller deliberately spends extra time finding the follow instructions button. I understand that some people are gonna say ATC are very busy with a lot of traffic and dont have time to respond to everyones requests, but they are literally going out of their way to spend extra time finding the follow instructions button instead of just pressing the default button saying unable, expect vectors. When you ask a question, you expect a response. The button that pops up on their screen by default is a response. Half the time they do not even bother responding or just continue giving you instructions ignoring your question completely.
Also they sometimes tell you to check tutorials on the home screen when you have not even misunderstood anything. Like sometimes I am flying into an airport and I request to descend on the star and request my approach, they dont even bother replying to your request, they just give you vectors. Sometimes you make a request for visual or gps or whatever on whatever runway they dont even look what you said, they just say ILS approach this runway. If you ask to change runways they do not even bother pressing the unable button that comes up by default, instead they tell you to look at the tutorials on the home screen. The change runway button is self explanatory, there is literally no way you can misunderstand it or learn how to use the button. Why would you need to look at tutorials on the home screen???
Sometimes, you may even get told to follow instructions when they havent even given you any instructions in the first place!
Expert server ATC have the power to kick people, but they are just players, exactly the same as everyone else. They dont have the right to boss people around.
