I joined some friends one night for a dance social. After the lights came on and the social was closing up, I was put in charge of making sure one of my friends made it home safely since he'd been drinking a bit. While getting him something to eat and verifying he got home, I remembered I forgot to take my drinks back to my car from the social (the social was BYOB). I saw the bag zipped up when the lights came on and the studio was emptying out.
I texted the host of the social about my bag and the drinks inside of it, including a list of all the bottles in the bag. My friend also sent a text to the host about the bag and the drinks inside of it. The host responded "I got it" and that I could pick it up the next day.
When I went to pick up the bag from the host 2 of the bottles were gone. One side of me says someone could've grabbed the bottles after I left, but another side of me suspects the host took them since he never stated there were bottles missing.
My question is: how do I avoid being offensive when I ask the host about the two missing bottles?
I want to know if the host did or didn't take my bottles without being abrasive or allowing my preconceptions to interfere. I do not want to accuse the host of stealing it, since he might not have done it, and I also might want to go to this dance social again.
