A 30 minute window for food seems weird, then I checked the article about 9/11 - it’s roughly the same times the first and second tower were struck (8:46 AM & 9:03 AM).
Still weird, trashy, and offensive. How could they possibly think this was a good idea? Putting out things like muffins and other breakfast stuff is standard at any decent hotel, trying to make it into some sort of complimentary muffin tribute though? Wtf Marriott?
Somehow it would've not been offensive if the deal lasted all day. If it only counts during the window of time where people were dying in mass, that's unnecessarily fucked up.
Somebody above linked the article but the explanation was that people gathered in the lobby around that time on 9/11 to watch the ceremony in previous years, so they brought out muffins for those people.
