The oldies over the street always take the taxi to the shopping centre at the busiest times.
Even I don't like going there when its busy, and I'm not two people with walking frames.
A lot of these oldies got so used to going shopping in the middle of the day they have never even considered going at a quieter time, though it would be better for all concerned.
You have the supermarket to your self almost in the first hour of opening and the hour before closing.
