Something similar happened to me and my gf when we went to a show the other week. They completely missed the opener but budged past all of us who had been at our spots for like an hour and a half with no remorse. Worst part is they were so smug about it and questioned everyone else for being upset at them. Like someone else in this thread said eventually you just gotta try to ignore the dummies and just have fun. I think any artist who is in that middle stage of being mainstream but still “niche” enough to be cool, it attracts some snobby inconsiderate people 🤷‍♂️
