So did this place lose customers after they started accepting credit cards or are they still cash only?   
  
 If they are still cash only that doesn't really make this a contrast.  My guess is a place that is good enough to drive 45 minutes to get to would be fine even if they bumped up prices to accept credit cards.  As long as their quality remained the same.

I believe the primary draw is the portion size to price ratio.  There are other Chinese food places nearby with slightly better food but their portion:price ratio is nowhere near as good.  If they had to raise prices I'm not sure they'd compete as well with the other places.
