Recognize that most seasoned VR users expect these glitches and don't take it personally. I usually throw out a quick text apology in local chat if I phase through someone, it's the digital equivalent of a nod. The lack of physical feedback means these breaches happen constantly, so the etiquette is still being written by users like us. Honestly, if someone gets offended by a VR collision, they probably haven't spent much time in crowded spaces. Just keep enjoying the show and don't let a bit of jank ruin your vibe.
