A friend of mine from the US came and tested positive.
He has 2 Pfizer's and a booster in the US. Negative test on the flight out.
He demanded to get another test and was told by the doctor,
sure he can have as many as he pays for. He can have 10, they can
all be negative. BUT, the first one was positive and that's the one that counts.
Wasted 7 days of his holiday, wasn't happy.
