I have encountered businesses that scams us before and it was such an experience. I was called by an unknown caller to receive something for free. And we got there to claim it. The result is that we could only claim the freebies if we would buy their product and not only that, there are other additional free items to give also. I was thinking if giving many freebies didn't make them lose their profits. So attracted we decided to buy their product and paid a lot just to get the freebies which later on we knew that we are still on the losing side because the product bought was overpriced. So I realized that something free isn't really free at all. It is because it's business and not a charity organization. When I see something like it I just laugh and never cared too much since then. So for me I no longer interested in free airdrops.
