Typing this in my phone so excuse the grammar and syntax. So last Wednesday, I was at dominoes on my phone whilst waiting for my order. A big guy who was twice my size (I am 16) busts into the restaurant asking for my phone, saying his gf was currently being raped. Who quickly tells me his life story, something like he went to prison at the age of 18 and his mum got raped by her uncle.
He dumps an iPhone 5, an iPhone 6 and a dumb phone on the table claiming he has no credit. In my mind I thought this was a mugging as how could someone possibly have the money to get 2 iPhones ( I also thought those phones were attained through previous muggings) not have credit on his SIM? Wouldn't it be easier to put on credit if it was that urgent?  What made me say no was the fact that he reeked of cigarettes, was bigger than me, and had a deep hoarse voice which was being used in its upmost volume. He also was definitely faster than me, as a general rule I don't give valuables to strangers who I think can outrun me. 

After my denial, he said " I understand your concerned for your safety, but you're also an ignorant pussy" and continues slagging me off for 5 minutes. He then proceeds to threaten me by punching me in the face. One of the lines I recall and will deeply reside in my mind is "I TELL YOU MY GIRLFRIEND IS BEING RAPED AND YOU DONT HELP ME!" which looking back now, I should've. He then says if I don't leave the restaurant he'll punch me, so I left. I walk around the restaurant to make sure he doesn't hurt the cashier, (I was the only one there). After a while the cashier gives him a phone and I hear yelling . Strange thing was he didn't call the police.

He stated that I shouldn't be around him, whilst he was having a fag near the entrance, I ask if I am now allowed inside to collect my order, to which he says yes after asking multiple times.
Whilst I collect my order I am told he lived upstairs.

I think I'm an arsehole. I think what I should have done was hold his phones for ransom whilst he uses mine. I was stressed, and put under pressure. In my only defense, I thought it was a  mugging, I don't ever trust strangers and he did come across as really dodgy. The area where I live is renowned for crooks, high speed chases and general criminal activity
