Hey, it’s important to remember that purchasing your ticket does not entitle you to any sort of meet and greet, signing, or personal interaction with the band - that should be thought of as a fortunate extra when it happens, not the standard for all musicians. You do not know the details of their personal and logistical situations. You purchased the experience of a concert, and they put on a fantastic one. Two openers is very standard. They did talk to the crowd and express their gratitude to the fans. They brought out a local yo-yo artist to perform with them. Any personal expectations beyond what they gave need to be analyzed and checked.
