I call it "The Fast Lane". The kids who work the drive thru here always get it right, are incredibly fast, and unfailingly courteous - without overdone spiels or orchestrated upsells. This is the best of the new (technology, efficiency) combined with the best of the old (steady, hardworking kids, unburdened by consultants keen on turning them into obnoxious 'sales associates'.)
Understated, bedrock service. Kudos to the mgr. Your guys and gals do a terrific job.
