Passengers: Smokes and Drinks are available with attenders, just ask them, they will be very happy to serve you for little extra. Sorry, I dont have the price list.
Non smokers AC travellers: Don't go to the door after Dinner. Keep in mind that few are very desperate and they dont want your wisdom.
Authorities: Please take action before it is too late. I saw passenger throwing butts in the garbage can and that could lead to fire accidents.
