I took my dad to see James Hare vs David Barnes at Halifax, on a SN show. We had to sit through 2 hours without a single bout thanks to the ambulance getting stuck in traffic - it was coming up from Birmingham, for some unexplained reason. Then the crowd at our side of the ring rioted, and my dad was really shook up. The MC got into the ring and threatened that the main event might not go ahead unless the rioting stopped. At this point, me and my dad were caught between the two rival crowds who were baying for blood. It wasn't just name-calling and drunken behaviour, it was really nasty stuff.
With the main event in doubt, we reluctantly decided to leave - this was after two hours of sitting on our backsides with no action in the ring (frustrations which wound up the crowd in the first place). Anyway, after a week had passed, I wrote to SN and expained the circumstances. I didn't want a complete refund but a partial refund for my dad would have been a nice gesture.
The response from SN ensured I will never buy another ticket to one of their promotions. They could not have given a fxxk; they had our ticket money and couldn't have cared less about the fact that we had sat there for two hours watching an empty ring, before getting caught up in some nasty rioting.
The thing is, I used to regularly attend SN shows, but I haven't done since then and I never will again.
