When I heard the news yesterday, it came across as green washing and a chance for a good headline. I imagine its a drop in the ocean of all the other disposable waste they send to landfill, but reducing some is better than none I guess.
Pre-covid I got in the habit of taking a re-usable cup with me to use on the plane or lounge...I always felt a bit pretentious, but haven't done that post-covid as people/businesses went through a phase of not accepting them.
