There's a few rituals when it comes to opening the pack, sacred rituals. You don't want to anger the smoking gods do you? The lucky is sacred for its immunity to being taken from you, when it comes to one left you can smile at your little friend, you know no one who takes smoking seriously will remove it from your grasp.
But the opening ritual is just as important, hit the bottom against the palm of your hand 3 times to pack down the cigs. Then proceed to remove both plastic from the top and bottom followed by removing front protective foil. The lucky is chosen in many different ways but the correct way is to hold the pack sideways and flick the bottom. The highest is your lucky and if you dare smoke it before the others then another must be chosen, if another is not chosen...may Tod (tobacco god) have mercy on your lungs.
Of course Tod is the tailor made god of smoking, i am not a follower of bags.
