if you are looking for philippine martial arts, a good way to see if this person is just going to teach you to swing a stick, or really teach you to kick some ass is to ask a easy question: can you show me how to attack somebody? most of the bulls#*t martial artist will only ask you to "strike me here" and then give you an answer. that is not learning to fight that is "self defense". most of the people who specialise in these "stick defenses" do not know how to fight, and cannot show to you HOW. find someone who knows how to ATTACK. that is practical application for the street. the guy who you will use you stick against on the street is probably not going to have a stick.
if you are concerned about will you have a stick, that is only a question you can answer. i carry the weapon i choose to carry that day so i can use it "just in case". if you are confident you can use the weapon, then carry it! i have seen these folding sticks with a spring in it, they are very good and will do more damage than a rattan, and if you know how to properly use it, you can kill somebody if you have to (dont go around killing people tho).
good luck!
