I don't know about allergies. I'm not knowingly allergic to anything but you may be correct. I appreciate you're enjoying the prospect of me suffering additional anguish from a force fed NB4L ride complete with ridiculous "disguise" but I doubt I'm that much of a sucker for punishment. ;-)

FWIW I have noticed feeling a bit yuck on occasions on brand new buses
and trains (and cars) of various types. It's not unusual for plastics
to give off more nasty vapours in the first few months (e.g.
formaldehyde), possibly you're sensitive to that and wouldn't get the
effect if you used one now.

The other thing that does that to me is newly installed laminate
flooring or MDF (but not once it's been down a month or two and the
vapour has reduced markedly). When installing it (which involves even
more being given off as it is cut) I get a noticeably tight throat,
too.
