Jacks - Again

OK - we decided to be brave and give Jack's drive-thru in Locust Fork, AL another try.

We placed our order and drove around to the window.  Had to wait a little longer than normal for a drive-thru, but finally the person opened the window, took the money and handed our drinks out.  Then he looked around at the orders sitting there on the counter, finally chose one, handed it to me and said "I think this is yours".

OK - he "thinks" this is our order???  Thankfully, the order was correct and the food was good.  So, I guess overall it was a decent experience.  It's just that I keep getting "stuck" on that phrase - "I think this is yours". 

Is this the way to run a drive-thru?  What do you think???
