Is it OK to photograph people eating onm the Tube?

Not really but is it really necessary for people to eat on public transport. Other passengers have to endure the smell of greasy vinegar laden chips, kebabs, burgers and once I saw someone dipping into a smelly curry. Buses used to have a sign about not eating food on them but that seems to have been removed, probably because it contravenes 'human rights' or something.
The photos I have seen of the women caught eating show them eating food that contributes to them being overweight as none of them were fading away.
