Hey, who showed up tonight but had to take off before we sat down to eat? I didn't get your name (I figured you knew Scotty since you followed him into the parking lot).
I hope we didn't scare you off by seeming unfriendly! We sat down at the table and thought you'd join us once you got off the phone and that's when we realized you weren't here with someone at the table. Everyone had assumed you were a friend of someone else that was there. Scotty went out to see if you were still on the phone but noticed you had taken off.
Sorry we weren't all that welcoming to someone new.
