they were saying :

One concern is the escalators. I have seen signs on some escalators
indicating that dogs need to be carried. As she is 30kg this could be
difficult on a long escalator. I can pick her up when get on and off
but it should be safe to put her down while traveling up.

Like the sign says. Dogs MUST be carried.

(You could always point this out to somebody without a dog and lend him
your Lab for compliance purposes. "Look, mate, I don't want to be awkward,
but it does say you have to carry a dog. And it just so happens I have one
here you can borrow")
