Class post!
I believe that Gate Gourmet's industrial relations problems have indeed spread to Barra and the staff are currently picketing the beach and stopping any persons who wish to have a picnic there.
Gate Gourmet also have the contract to supply the Terraces, and in view of the dispute, catering is now being provided by the local Tesco. Sadly there is a beef shortage and only egg mayo sandwiches are currently available.
Quite why you comment about the Terraces though I'm not sure. Perhaps you're a little confused and did not know that BRR has a Concorde Room with an access policy of nothing more that a Gold card and a paid ticket. Food is Fortnum's hampers flown in specially and drink is c/o Mr J Walker.
