Geoff, having been a punter there for many years, the show does go quiet early afternoon, but this year, the departure of people seemed to happen earlier in the day. I am guessing those traders that packed away knew from experience that there wasn't enough spend left on the ground to keep going.
Nice to see a new company at the show. I thought your buildings looked very good and were handy because they have a relatively small footprint, while still possessing presence.
