If the leaky door-seal problem is so endemic, one would question the maintenance-regime that doesn't ensure a firm seal (adjustment!)
Secondly, stuffing blankets in the gap is hardly a "professional" fix
to the punter it looks as it is...a CC trying to hide a gap with a blanket....presumably said blanket isn't Certified draught-proofing,-so, why not an extra-long "snake" as used in dwellings oop here in 't north,when t' draught under t' door starts shuffling the furniture.
Said soft textile snake could be covered in corporate colours and look as though it was a proper OE fitment/accessory. Pax then wouldn't give it a second thought.
Kleenex/towels/blankets are a BODGE however nonchalantly they're applied.
Don't say they're not effective, but IMO, shouldn't be needed in the first place.
Daily wail is just an entertainment rag aimed at "Angry of Tunbridge Wells"....why get worked up about it?
