I try not to be a snob about tea, but I do (well, did pre-pandemic) carry my preferred tea bags in a darling tea wallet, just in case the selection in a restaurant was not to my liking (I can't stand Earl Grey).

I was in a diner once and when I ordered hot tea, the waitress asked "Barry's or Lipton?" I chose Barry's, as any right-thinking person given that choice would, and then asked "Does anyone actually pick Lipton?' She said "Once."
