Quite frankly it's only the top pair or two who rarely misbid at club level. If you're not willing to accept that most players are there for a good game of bridge played to the rules, and you're not interested in trying to keep their evening enjoyable, why go?
Irrespective of whether this was a fielded psyche or not, complaining about psyches while accepting the many many abuses of the rules that take place in clubs is, quite frankly, pretty pathetic imho. If everyone played strictly by the rules, and that includes psychers informing the opps about potential IPUs from previous experience, then I suspect everyone would be able to enjoy their bridge, not just the rule-breakers who are there for "kitchen bridge".
