I overheard Steve booking the room, but didn't hear Akira's name.
Walking over to the woman behind the counter, I asked, "Excuse me, could you tell me how many are in our party, just booked by Steve?"
When she listed the names, Akira wasn't there, so I added on more to our party. Now i was annoyed with Steve.
(Can we stop with leaving people out? It's not really a good story flow-er.)
