Well you're obviously happy to attend events that don't care about your safety.
Ive been to the same events, Ive even played a tournie with Liam. Its too easy for you to just jump on this and say these events dont care for our safety when it is OUR own responsibility to make sure our tanks are in date.
Bare in mind that an in date tank can be damaged and dangerous, but still in date. What is the actual point of checking tank dates at a tournie? It should be a full visual check of the entire tank and a date check in that case. Im willing to bet that your "safe" events you attend dont so this, so by virtue of your own wisdom, your events dont care for your safety either. They do the minimum to get by.
Or are we jumping the gun a little with an over reaction?
