I agree with that. If you roleplay in the 'open', so to speak, then you are hanging a big glowing 'feel free to join in!' sign for all to see. You don't get to complain if people then intrude in your interaction.
Still, I've seen it happen, so I know such people will exist. Asking for permission is a win-win in any case: if they are open, they will quickly reply ''Sure! Get on board!'' and you'll jump immediately ot IC mode; if they are not, they will tell you so and you can continue without experiencing a bad time.
