mwb2paris: I ate at the same place in PHL on 11/8, but noticed no knives at all, for me or anyone else. I was wondering how they prepared the obviously sliced-in-two wrap-sandwiches or how the lettuce gets cut. Perhaps with captive-knives as hauteboy observed.
As for your "Dennis Miller" moment, based on my experience there, you could add "PHL-Security" to the long list of infamous oxymorons.
