transfusions maybe.
That has happened for sure. Does it still happen? They look pretty young. I would hope most blood transfused today is clean, but I'm not sure.
In fairness - you can't get HIV from eating food. Also, the HIV/AIDS scare was a bit bullshit - and brought to us by Dr. Fauci too. A straight man would need to have sex with 2,400 women with HIV to contract it. There are only something like 8,000 women in all of Canada with HIV. Yet 30 or so years ago people thought you could get AIDS from kissing, lol.
I would eat at their AIDS infested restaurant. No problems there.
