LOL▸ - yes.
And I've been caught out many a time.
I queue up at the other end of the platforms, the Hammersmith/City tube line end.
I'll be stood there, with the rest of the waiting posse, in pre-surge stance.
I'll look away, either down at the trains, or at my watch or something, and when I look back, the surge is already in progress....and they're all walking, but I never quite know which platform they're surging to, so I stand, and wait, and watch gormlessly at the departure boards, waiting for it to cycle back onto page 1 so that I can see what platform I should start surging myself towards.
