Actually, Heathrow on the return (on Monday) was just as bad. After
waiting at the carousel for over half an hour they announced that the
plane door had jammed and bags were only starting to come off. That was
a lie, since I'd seen lots of bags with my flight number already.

It might have been true: there are both forward and aft baggage holds. It's
perfectly possible that one might have had a jammed door. Indeed, it's much
more likely that one, rather than both, might have a problem.

Then "some bags have been delayed as a result" would have been the
truth. "The bags are only starting to come off" was a lie.
