I opened this thread expecting some crotchety guy to be saying how bad it is that people wear shorts, t-shirts, and flip flops in first class and was prepared for my reply that many times those outfits are nicer and cost more (I realize price doesn't bring class but) than the buy 1 get 8 free Jos A Banks suits but then I was actually offended by what the OP actually experienced. However, this has nothing to do with no class in First Class but no class on an airplane. Even the peasants in Y shouldn't be subjected to this.
