Free is most abused word

Yesterday, I was offered a free chocolate box at RiteAID pharmacy.

Why ?

"I don't know... my manager told me to... it's free.." the clerk said.

I have no idea why they do that - not know why they give off a $7.25 box for free.

I did take the box suspicously. It neither made me thankful, nor grateful nor loyal to RiteAID.

In fact I grew suspicious of them.

Did "FREE-CHOCOLATE-BOX-SCHEME" designer imagine that it could have negative experential response?

Hugh Macleod offered to include my(anyone's) blog-rss on his bloglines.

Did you also think the same as I thought,

"what's the catch ?"
