figure this the way i figured it:
1.99(30 minute wait) versus 2.69(no wait) at the QT i used yesterday.

in my 10 gallon tank, that would save me $7.0 by going to the cheaper station where i wait for 30 minutes, and get angry, risk fender benders, and waste MORE gas by idling and using ac.

im sorry, but i make more than $7 in 30 minutes at my job. that is how i determine that that stations special is a waste of my time, not to mention the other side effects that come with wasiting in heavy traffic as i mentioned above.
