I was in WT+ one time coming back from DXB and a chap in CW wanted to swap seat with me to be near his wife and children, the crew asked me and of course I agreed. However i did complain like hell when they served my economy meal along with plastic cutlery. The rubbish food was one thing but to still serve it with plastic cutlery seemed to very petty when all around were using proper cutlery.

So perhaps you can even expect your G&T (or whatever they are currently serving) to be brought back for you?
