What about the screeners that aren't aware that you are allowed to wear disposable footwear. TPA airport provides paper slippers, which I grab several of to use on future flights out of airports that don't supply same. I had to argue with a supervisor at EWR to let me wear them through. He said NO FOOTWARE, disposable or otherwise was allowed. When I tried to explain they were from another airport, his response was, "well it is not allowed here." I asked him to please recheck the TSA rules, and after making me wait for 10 minutes, said it was OK for me to go through. I just had a similar incident this morning at Las Vegas. They told me "slippers" are not allowed. When I said they were paper and TSA approved, I was finally allowed to pass.

Even TSA agents have no idea of the rules
