Ahh and I went to the same popiah stall again! This time I went with my father and we sat at the same spot which was quite far away from her stall.(Not on purpose) And this time, she brought 2 pairs of chopsticks! I looked carefully, and saw that indeed, she brought with her two and only two pairs of chopsticks!

So it's not true that she brings extra chopsticks around with her. Well of course you can propose that she brings a random number of chopsticks with her, and that the number of people corresponded to her number only by luck... but seriously lah.

Oh and I think there is a rationale in bringing the same number of chopsticks as people! Not just for the reason of good service, leaving a good impression of her stall, but also subconsciously more people at the table would eat her popiah.

For example, if I buy 1 popiah and at first I didn't intend to share with someone else I'm with (but I wouldn't say it out), then she brings 2 pairs of chopsticks. Out of courtesy I MUST offer to share with that person rite? Otherwise it would be just weird. The other person would also find it harder to reject.

Also, if I originally intended to share with the person but I didn't say so, having the correct number of chopsticks would facilitate sharing too, because sometimes people reject the offer to share because they don't want to share chopsticks, and the other person doesn't feel like grabbing an additional pair. In effect, having the correct number of chopsticks results in more people getting to try her popiah.

Which is a good thing too! Her popiah is nice...
