I've never 'got'

I think there should be a disclaimer on all menus for coriander, like the "this dish contains nuts" one.

Yeah, that is not a bad idea.

Once had a pork salad at a Thai restaurant. When ordering the waiter asked if I've had the same dish before. I found it a bit peculiar, but she explained that the amount of coriander in the salad just does not sit too well with lots of people.
