I agree—that is difficult. It takes me back to discussions around Challenge 25, which we have mentioned. It started out as Challenge 21, and the age was raised because it was very difficult to tell the difference between a 21-year-old and an 18-year-old. Technology is evolving in this area. There are new things. We know that members are using new forms of technology to help with that. They rely on things like Government-issued ID. There are various ways of challenging someone. It comes down to things like the training and how the consumer is around the till. Are they acting nervous or like they are up to something? It is then down to the retailer to use the training that they have been given to check the ID and use their own in-store procedures, as well to try to operate responsibly.
