As an insider, I totally have seen this. On Black Friday, 2022, my Hospital set up a booth at the local mall and we're giving out $50 gift cards to those 13+yo who took a booster on the spot, and $100 gift cards to those 12yo or younger. This was long after the signal was very clear that the Jab was causing heart issues, especially with the young. Let alone the fertility issues that have been demonstrated. The money for Gift cards was given to the hospitals as a Grant from the NJ Gov.
This specific targeting of children with these higher dollar value GCs really pissed me off. It was part of my decision to begin working my way out of the truly evil medical industry.
