COSTCO no longer wants motorhomes in gas lines?

We stopped at a Costco with our 40 foot diesel towing a car. Yes, we took up all three pumps but the station wasn't busy (not in Calif). The attendant didn't say a work other than "nice rig". The only odd thing was the car with older ladies in it who waited behind us instead of pulling into one of the open pumps! Guess they really like the outside pump. And yes, some Costco's sell diesel.
