I just saw that on the news....funny thing is that it may hurt the airline more than they thought, because if people refuse to pay to go, they may decide not to drink as many beverages, so they lose that money as well!
You know, if they just raised the stupid price on the ticket by a buck nobody would notice! How dumb is it to announce that you're charging for using a restroom???
I remember once that one airline removed parsley from their meals and saved several hundred thousand a year. Poor parsley farmers, though....
