This was a huge debate this past week with my husband who didn't want to wear pants in the 100 degree heat but doesn't have shorts that cover his knees. He wore the pants, but continued to point out just how many men were in shorts that didn't cover their knees and "they were not being turned away". I agree with the "respect the rules" part of things but if a venue is going to relax the rules due to the extreme heat, then that should be posted or at the very least, followed consistently.
