<human>: Condense the text into a few key points

So I've been in contact with a band and everything seems to be going pretty well. Before I signed them, I wanted to see them in action. I live out of the state, so my mom and sister offered to go see them for me. I emailed the band member and asked if they had any public show cases coming up for my family to come see them play. He said there was one coming up in a few weeks, and he would take them to dinner and everything! I thought it was great! I reserved a hotel for them (it's still a 3 hour drive from where they live) and asked for the gig location. Turns out it's someone's wedding reception! Am I crazy to think this is totally out of line? I would be livid if the band offered strangers to come to my wedding. Is this a normal thing do? The fact that he even offered makes me want to just write them off all together. They were pretty much the only band we have seriously considered! Should I email back and ask if they have any public events, or just forget about them? Advice needed!
