The last message I got from my nephew, over an hour ago, was that they were "waiting for the dog handlers".
If these are his last words, I will know the correct response next time will be "Oh no! Not the dog handlers!". Most likely, it sounds like the dogs have been bumped.
He didn't seem to mind. I was getting lovely messages like "I just found out I get 2 4-course meals" followed by "I've been informed of the all-night snack bar where apparently they have luxury cakes". I did tell him that the kitchen at home was probably a more interesting all-night snack bar, but he wasn't having any of it.
