Never leave your bag unattended on the bank of shopping trolleys or on pushchairs.
Always make sure that your bags are securely fastened.
If your bag has a strap, wear it across your body with the openings facing inwards, and hold it close to your body.
Never put your bag on the floor to look at anything on the shelves or when trying on clothing in changing rooms.
Only keep items in your bag that you need, and leave other valuables in a safe place at home.
