Rampers at DFW has been one of my biggest complaints with this company. Really embarrassing when parked sideways so that half the passengers on the plane can see their lackadaisical attitude towards their job while we wait for them to mosey into position AFTER showing they show up 5 minutes late. That said, on my last sequence, I was so surprised with how improved they were for the entire sequence, I commented that there had to be a change in management for something like that. Captain agreed. Hope it's permanent and not some coincidence.
