T&B
I was told categorically last month that they would not allow that.
They open the doors at 0800 and I have more than once got there at 0800 collected my ticket and then headed off for breakfast.
They don't start serving at PLD (or L&TS) counter until 0830 though.
Perhaps they were all in the canteen ?
In fact guess where I am off to tomorrow for 0800 !
