So your dad will only shop at Sainsburys despite having an Asda on the doorstep? I don't get going to a supermarket at all. We've had groceries delivered once or twice a week from Sainsburys, Ocada, Tesco, Asda, etc for about 10 years. The concept of walking around a supermarket on a regular basis fills me with dread - all that wasted time and effort.
