I know that attendance is never guaranteed at these things, but I exhibited at a trade fair today and over the 5 hours only four people came through the doors. None of them were remotely customer material.
Most of the other exhibitors walked out early and the organisers wouldn't engage with any of us when we asked what had gone wrong.
They had previously told me that they'd sold over 100 tickets in advance and were expecting a healthy walk-up on the day. They'd also sent us a schedule of all their advertising and other pre-publicity which looked pretty healthy to me.
I paid a fee to be there and along with my display materials and travel expenses I'm pretty well out of pocket.
It's only my second ever trade show so I'm pretty new to what my rights are but bloody hell
