McDonalds - I ' m lovin' it

The evaluation of service or product can be so easy - don't need to be extraordinarily difficult if one is just thinking a bit outside the box.

McDonalds is just doing this in at least one of their outlets in Damansara. They have a simple Smiley Box standing there where one can put in tennisballs. Two choices are given - either you like it or you don't.

Of course, they won't know why someone is happy or unhappy, but they might get a quick feedback if what they are doing is working. If it is not working, they can implement something more elaborated.

What do you think?
