I don't think he likes being pushed that way (who would?), but he won't say it because at that point it's too late and he's tolerant overall. That's probably why he lets people do what they want. He'll show when he's annoyed, discretely. People self-absorbed by their phone won't even see, and if they see they won't care. We're not in his head, and we weren't at Gilman either but I think there are big differences with that time, people jumping on stage to assault him with their phone (and by doing so, not even looking at him... but at their phone) nowadays, they're crazy fans, but I wonder if they aren't more crazy about their social media than about him. They just want to have that picture they'll post and the rest passes after. If they weren't any phones brought up, there wouldn't be that much aggressiveness. I think Billie understands all this and is glad overall to offer this experience to people, but he keeps telling and showing that he doesn't like the overuse of cell phones (and the careless behaviors that go with it), but not only. He doesn't like people touching him just as they see him passing. He's kind enough to never get mad at anyone, he surely understands how people feel but still tries to set his limits even if people don't always respect them. I think the fact to set his limits helps him to stay tolerant, and is like a a warning for the times he isn't disposed to greet people's marks of affection. In that way, I really feel it's the whole of fans that pays for the few people who really aren't respectful.
Last year at my previous Longshot show I had spoken to another French girl I met there, she said to have attended 8 or 9 Longshot shows to most of which Billie had come out to meet the fans, and that at none of them the fans were respectful towards him. That was after I said that I regretted not to be able to meet him after the show. Just because Billie is overly kind to the fans he knows to have made a lot of efforts to come to see him, doesn't mean we should consider that he senses differently a behavior we can ourselves feel, with our own eyes, to be disrespectful. For me, anyway.
