So recently I was eating lunch at a fast food restaurant and doing my homework at the same time. I had my earbuds in and felt a tap on my shoulder. When I looked back to see who it was a big guy wearing an old torn jacket asking me if I had money to help buy his lunch. I said no and put my earbuds back in he tapped me again and made up a sob story about how is mom was in the hospital. I just said no again and put my earbuds back in. The third time he happed me I got really pissed because I had already told him no twice and after the second time he had gotten close to me and closed off the exit from the booth (I think he was trying to intimidate me). So I angrily took my earbuds off stood up and aggressively told him to back the fuck off. Once I said it he backed off and left me alone. But a few of the people in the restaurant gave me a dirty look and i felt bad. So reddit AITA?
