Didn't stop you from using Uncle's nicer facilities though, did it?
Certainly at Incirlik, it was a requirement to show one's tatty old NTO to the person on the checkout if buying alcohol at the Class 6, to prove that you hadn't exceeded the ration allowance which she'd stamped on the back the first time you visited. This could be a nuisance it you went back more than once a year, as was often the case, as it meant getting the Adj to produce another NTO.
The French had a simpler solution. They just photocopied their NTOs if they ran out of ration points - and had made their own stamp. The Class 6 folk never noticed......
