You get a feel for this when you play at a club. It's a personal space issue that you learn over time assuming you're a complete sperg and don't understand it right away. It's the same kind of thing and how to behave in a lineup or sitting at a bar or similar. There is an acceptable distance and angle and there is unacceptable distance and angle. This specific situation is pretty funny. I've never had anyone do that to me before.
