Bringing food was a little more successful. I was able to avoid both having to purchase food at exorbitant prices and also the dreaded styrofoam take out container. (see left)
While in the airport, I saw the following amazing item (at right): a toilet with a rotating plastic sleeve to keep your tushi from touching the toilet seat where other people have sat. This has never been a big concern for me, but apparently it is for others. I chose not to push the button to rotate the plastic sleeve. Thankfully, it wasn't automatic!
