I was strolling near the Notre Dame Cathedral. Two women came up to me asking that I just sign a sheet of paper stating my support towards an organization that helps kids.
They insisted that I sign the sheet, once I did, they started demanding a contribution. They said since I had put my name down, I had to donate some money.
It was pretty daunting and they conversed with me for another 15 mins trying to get me to pay up. But thankfully, I was able to walk away after stating I had no money since I was a student.
