Looking at this change it is obviously a transition away from free breakfast. I anticipate there will be little interest in the Continental Breakfast offering that is given (I mean, many of these breakfast bags are so bad they aren't even worth taking) and ultimately that will be quietly dropped. Maybe they will throw a bowl of bananas and a few shrink wrapped defrosted muffins or danish next to the free coffee to at least say they offer "something" free.
One thing you can say for this is at least in the US it appears they will be doing a consistent offering from location to location after they get past the pilot period. A lot of other chains are really struggling with consistency on the breakfast program right now.
