I encountered this before, at the very same place. Not sure though. Someone giving sample of local delicacy and offering for sale later. Before it was buko candy. Now it is buko pie.
I am skeptical for two reasons. First is hygiene. He is giving out thin buko pie slices partially lined with cellophane. The pie was prepared by him or by someone but he is sure slicing and wrapping it in public place. It might catch all sort of dirt and microbes present in that area. I am currently in air-conditioned bus. Someone here might have a severe cold and cough.
The buko candy from before was well wrapped. Worthier of trust than this.
I once suffered diarrhea after drinking buko juice while on travel. Thankfully, I arrived home before the symptoms manifested. I treat every buko and products with precautions when I am on trip.
The second is appearance and flavour verdict. The vendor clearly said, you may buy later if it passed your judgement. It happens not. So sorry!
It is nowhere near the thickness of best buko pie I have eaten so far. The taste is inferior either. The best was from Laguna, by the way.
The marketing strategy, however, is effective depending on product flavor. If majority of people who ate like it, then more will buy. To taste is to believed. That’s the idea. We have been using it with great success every product exhibits in malls and event areas.
