You never know when delicious chick will ask you for light...
You never know does she have corkscrew and sharp knives in her flat (+ worn scales means you are stable and serious man)...
...and if she has clean cutlery in case she decide to feed you (+ titanium is the only metal that tissue sticks to)
Be prepared. Every Day Carry those three.
