Yes, I believe it's real. That is, I believe it's real footage of a real supermarket (I don't think the supermarket, and the people in it, were staged for the video)

Do I think it's for all Venezuelans?

No, I don't.

But I wasn't sharing the video with the intention of pretending that those who are starving and having no rehydration do not exist.

If you think that's why I shared it (which it sounds like you do) then you're mistaken.

I shared that video just to show that some supermarkets have produce on their shelves, which could be looted.

(in response to the comment about "What are they looting? empty racks")
