Leclerc has an anti-theft policy that bothers me. Having back problems, I carry, for handbag, a backpack of about 10l. It is the only sign that requires me to wrap my bag in plastic, thus preventing me from keeping it behind my back.
On the other hand, women "also more feminine", with larger handbags with shoulder straps, come in, without difficulty.
I find it discriminatory.
I am asked for a medical certificate. I imagine the doctor's head!
I add that I have never refused to show the inside of my bag as is the practice in other brands.
