Who would you contact? In a supermarket, some random staff member will look at you as if you had two heads.
Might have more luck in a small book store being able to talk to an actual responsible staff member \ manager.
Dunnes in Donaghmede is the same, it is ridiculous. You could walk around in a t-shirt in December.
I wear a gilet \ waistcoat and put my keys, phone etc into that. I wear a battered old rain jacket getting from car to shop and take it off and leave it in my shopping bag during the shop.
