I doubt the DHSS here would have been particularly surprised if they came up against it. A friend of mine works for them and has told me many examples of the cheek of some claimants.
I remember one where he had an Asian man arriving to collect a comparitively hefty benefit payment, the Asian reference is only there as what had enabled it to continue for some time was that nobody had questioned it until my friend noticed that the claimants name was a female name. Many of the counter staff were not Asian, and not realised this fact, not being familiar with Asian names. It turned out the claim was originally his daughters, his reason for collecting it was that she had recently started a well paid job, so obviously was in no position to come and collect her free money from the Government during office hours, so he was just collecting it for her!!!
That seems to be the mentality of quite a number of claimants, so I'm told, it's just free money that we can get regardless of any other income.
