Who's here?

We had an after-work office get-together tonight in a part of the SHAPE Club we had never been to before. One wall was hung with personalized pewter beer mugs. There was SACEUR's mug, his deputy's, the chief of staff's, and one for each of the NMRs (national military representatives). They were almost all still hanging there, meaning they were unused. Conspicuously out, and therefore in service, were the mugs of the Czech and the Slovak NMRs.

It's funny if you know what great beer-drinking nations the components of the former Czechoslovakia are.
