@ehBeth,
It has been seriously considered at several points over the last 2 decades because they know that there is a market, high profit margins on breakfast, and to boost the 1-3am segment at 24 hr stores. It has always failed to make it out of the idea phase because of cost to implement, increased food waste, and slowed down service.
Another reason why I wonder why they would do it now is that they dont think that they can get more traffic because of the increasingly crowded market, they think that they need to get customers to spend more on each trip. This is why they keep trying to sell more expensive deluxe burgers (and failing). Breakfast is a lower cost menu, the only way this works to get check averages up if more people trade up to breakfast from the $1 menu than trade down from the regular menu. Another problem is that the breakfast menu is high fat high salt, which takes it away from trying to be seen as food that wont kill us.
THe fact that management is doing a thousand new things to save itself often not well, has not been able to articulate a firm and sound turn around plan, and that what it does say is often contradictory makes me think that they dont know what they are doing.
