McDonalds always gives me a stomach ache. Wendy's doesn't however, and their food tastes better (cept the nuggets, but they are way cheaper than McD's).
Oh and read the whole article, it says they haven't fired anyone or hired less people at the establishments they are running these tests at. They have been reassigned to do other jobs like give the food to people, help them with the kiosk if they are having trouble, etc.
I think it's good because if they're short on people they'll be able to focus more on the kitchen (happens here now and then, making for slow service), you may even be able to place your order and sit down to wait for it (ala Culvers & Fazolis) and they might be able to focus more on keeping the place clean.
Though I still don't eat at McD's too often unless I'm not eating much, but perhaps this will cause a trend among other fastfood places.
