This one asks several questions. 

First of all, are they really selling a quarter of a cheeseburger?  Does that mean that For $3.00 (and I'm assuming that the 3 means three dollars) you can get half of a cheeseburger?  That seems a little high to me.  I mean, it doesn't not mention that it could be a quarter pound cheeseburger.  It just mentions that they are selling a quarter cheeseburger. 

The second question has to do with what they are selling. 

Is it truly a Cheeseburger?   (That would make sense.)

Or do they mean Cheesebugger? (whatever that might be)

Or is it a Cheesebouger?  (and that would be disgusting)

At any rate, I might think twice before eating at Hardees.
