Today I purchased the Prog from WH Smiths in Huntingdon, using the self service till, as I do almost every week. However the routine was slightly different today as when I scanned the barcode a message popped up saying approval was needed...apparently the Prog is age restricted and you need to be over 18 to buy it! Never had this happen before and I assume it was some database quirk...but I just wondered if anyone else had encountered this?
