WOW this is a long thread, and I've taken the time to read about 90% of it (well, up to page 7 anyway!), and my only comment is, whether CW were correct or incorrect in searching your bag, the very least they should have done is to have carried that out with tact and diplomacy, and something that is missing sadly in this world, politeness.
There just is no excuse for rude or impolite behaviour. Considering how much cinemas are supposedly losing out to downloaRAB, home DVRAB etc, you would think they would be trying to entice people back with, if not decent prices, at least decent service, but they seem to be adopting a version of the Michael O'Leary mantra. He constantly drones on about "if you pay a Euro for a seat on Ryanair don't expect decent service." Seems (some) cinemas nowadays adopt the position of "if you want to pay overinlfated, exorbitant prices to see a movie in an environment where you may not even be able to watch it in peace, dont expect decent service".
Something to be learned here?
