Does Racetrac have a continuous "Free Drink" policy?

There have been many of times I was in the store, someone goes to the counter with just a fountain drink or coffee, and the clerk says no charge. I've been asked many times when walking through the store with just a fountain drink, "Is that all you are getting?" Just this evening, the clerk asked me the same thing before I grabbed a couple other things, but she didn't charge me for the drink.

They use to have a week long free drinks (fountain & coffees) but they haven't done it in a long time. I wonder if they just stopped to free drink week and just gone with free drink as they please.
