PizzaHut Brand image

PHD Cool? PHD is belong to PizzaHut corporation, launched since 2006.

D stands for delivery.

Pizza Hut can court as general class food brand, familiar with by most HK people.
But how about PHD?

Personally, I think the image of PDA in the above banner doesnot match with
current style of PizzaHut. Perhaps, It wants create new prospective to customers.
However the idea impression is what?
The black mouth and glasses can not communicate the friendlyfeeling,
and also can not show the cool and trendy image for delivering staff.

It is little bit strange.
