Tik Tok algorithm is interesting

I don't know how Tik Tok does it and honestly I don't know how its algorithm works. It can't be algorithm though.

I just went to get a quick bite outside and got myself a $2.99 Jamaican beef patty. I paid with cash, didn't use my credit card. By the way, I also didn't bring my cellphone with me since it was just a very short distance, just a short walk. I had no electronics with me at all. Somehow, when I opened Tik Tok on my wifi-only tablet with no cellular connectivity, which I left at home, a few minutes later it displayed a video about a Jamaican beef patty. It's really strange... can't be a coincidence.
