Maria Palma on Her Blog talks about a possible solution to better service. Would a reward system work in most businesses?

I commented that Macy's had an interesting reward policy, in that they had staff members write their names on the bottom of the receipt, so you could go to a website and rate their service. The trouble was most of the staffers scribbled their name so illegibly, I couldn't have raved about them if I wanted to.

What's your take?
