As a stockholder who doesn't eat at McDonalds, I'm concerned with the latest announcement to simplify the drive-thru menu to only the most popular items. I think this will only serve to irritate customers who know the menu and are irritated that what they want to order isn't available via the drive-thru. It's like the decision is saying that McDonalds believes its customers at too stupid to handle the full menu in the drive-thru. The change may slightly improve the efficiency of the drive-thru, but I believe it's going to reduce sales significantly. People will be more likely to go to one of the many other drive-thru fast food options than park and go inside for what they want to eat.
You have a far too short-term outlook if you're concerned with the stock falling back a couple of dollars the last day or two. Go enjoy a craft beer (or two) and just focus on the simple fact that Habit will have 20% more restaurants a year from now. Keep perspective!
For the Habit that opened about 6 months ago near me, it's obviously doing better business than the In-and-Out that's about 100 yards away. The Habit always seems to be full. The Saturday before last when I went the line was out the door.
