Hi Oscar,
Read back should be within seconds, so half a minute is really a long time. Particularly on radio it is very irritating for everyone, when someone decides to take his time before read back. Everyone is holding their requests to keep the channel free for the person to read back. I generally give them no more than 10 seconds.
You may want to try this experiment: Deliberately wait half a minute before every of your read backs. You will notice yourself how long that is, and ATC will tell you to read back more quickly.
Entering the runway may not be a big deal in this case. But if this person does it here, he does it also anywhere else where it is a big deal. Therefore it is good to take the time to teach him in this non-critical situation. But when the guy comes with a smart-ass remark, indicating that he does not want to learn, then it is game over for today.
Game over is again a learning moment (it only lasts for the current session). Ask yourself the question: What did i do wrong? And learn from the answers, so next time you do not make the same mistake again. Or you can choose to start yelling, indicating that you do not want to learn, and make the same mistakes over and over again.
A controlled area works by certain rules, you really need to know when entering that airspace. Doing some homework in advance can help you a lot. Daweed made a post on the other forum with links to some useful documents.

Jomo chooses this so to give beginners a chance. But when they are not interested in learning to adhere to this most basic rule set, there are not many options left, are there?
Kind regards, Vincent
