According to NM, Kirsch has been accused of spreading misinformation about Covid-19 during the pandemic and continues to argue that the vaccine against the disease causes deaths.

Now, in a post on Twitter, the man reported the moment he tried to make the woman remove the mask she was wearing.

"I'm on board a Delta flight right now. The person sitting next to me in first-class refused $100,000 to remove their mask for the entire flight. No joke. This was after I explained they don't work. She works for a pharma company”.

And he added: "I explained that when she removed the mask to eat and drink, she could be infected". On the thread of publications, the man continues to explain that he even started the offer with $100 dollars (94 euros).

Most comments stressed that it is an unreasonable and somewhat frightening proposal. "Women don't want to make deals with creepy men on planes. It's not complicated," wrote one user. Others pointed out the lack of sense in the request: "What if the person goes to visit an elderly or severely immunocompromised family member?".
