O.M.G. What a ridiculous mess.
Some people are nice. Some lines make sense. But more often it seems that the nicest people are stuck enforcing the stupidest rules, and the reasonable rules are enforced by people who literally go far out of their way to be total assholes. Geez!
With apologies to all the many hardsuffering comicon employees who try to be nice, if people would just let them.
