He threatened you with violence bc you wouldn’t give him $20 - that is attempted robbery. He also touched you without your consent and tried to constrain you. You are not exaggerating. In the future, don’t wait five seconds. Just leave immediately. And if someone touches you, scream loudly and don’t stop. I recommend yelling exactly what they are doing at that instance “I DONT KNOW YOU, DO NOT TOUCH ME” so that the other people around you know what is going on. They are looking for easy victims. And also - never assume that they are acting alone. There could be others waiting.

I was in Newport Mall back in July - I will never go there again. Right outside of the Cheesecake Factory, a man firmly grabbed my arm and then groped my breast. I immediately started screaming and then other shoppers came and walked me to my train.
