It's through constant training and awareness. We use every opportunity available to us to make sure that the message is clear. Our “keep an eye open" approach and training for our employees is very clear. The first skill that they use is diffusing. Suspicious issues are to be reported immediately. Our operations control centre is directly linked to whatever police forces or support that we require in any event. We test those measures regularly. We use the feedback from our front-line employees and our managers to consistently review any of our processes and procedures to ensure that a balance is reached. When in doubt, always err on the side of safety.
