In my area, light purple or other not-in-nature hair color would be more common than natural red hair. It is more likely that you were recognized as the shopper by a vigilant store manager who consistently reviews the tapes after a shop report comes in. They nearly always list the time of the shop, so it's easy for a manager to locate the shopper. That's why it's a good idea to change styles routinely when shopping; business casual to jeans and tees to a nice skirt and blouse; no make up, a little too much make up; hair pinned up, hair flowing loose, hair in a tight pony, hair parted a different way; no glasses, reader glasses, sunglasses......you know the drill. :-)

When I am an old woman I shall wear purple
With a red hat which doesn’t go, and doesn’t suit me.
And I shall spend my pension on brandy and summer gloves
And satin sandals, and say we’ve no money for butter.
I shall sit down on the pavement when I’m tired
And gobble up samples in shops and press alarm bells
And run my stick along the public railings
And make up for the sobriety of my youth.
I shall go out in my slippers in the rain
And pick flowers in other people’s gardens
And learn to spit.
You can wear terrible shirts and grow more fat
And eat three pounds of sausages at a go
Or only bread and pickle for a week
And hoard pens and pencils and beermats and things in boxes.
But now we must have clothes that keep us dry
And pay our rent and not swear in the street
And set a good example for the children.
We must have friends to dinner and read the papers.
But maybe I ought to practise a little now?
So people who know me are not too shocked and surprised
When suddenly I am old, and start to wear purple.
