Mr.mafia doesn't scare me!

Two

Let me introduce myself properly
I'm Kimberley grey, I'm 18 years old and attend collage
I'm studying architecture and design
My bestfriend is Kate Oliver, she's also 18 and attends collage doing child care
I have brown hair which has loose waves, big green eyes and little dimples that appear when I smile.
My favourite colour is baby blue
My favourite food is pizza (any toppings)
My mum is Olivia grey, she's a 38 year old alcoholic
We often argue and never get along
We live in a small two bedroom house that I pay all the bills for by working in a cafe everyday.
That's basically a sum up for you all, clearly there's plenty more to find out but that's for a different time
I bet right now you just want me to shut up and tell you the bloody story
Okay, okay
Here it is.....

Ding
The little bell above the door rang signalling someone entering the cafe
I looked up from my phone since I was texting Kate
She was still going on about how hot Alex smith is and how she would fuck him
She's in love apparently
I shoved my phone in my pocket and looked at the man who was already sat down in the booth
I gave him a friendly smile but he just looked back at the menu
After waiting 5 minutes I walked over to him and asked what he wanted
" I will wait and order, I'm expecting someone else" he replied.
As he looked up at me I noticed the big scar running down his neck, I couldn't help but wonder what happened to this poor guy. He must have noticed me staring since he pulled up his coar collar covering the scar.
"Oh, ok no problem" I said before walking away
About 10 minutes later, another man entered
He had dark shaggy hair and looked a bit dirty although his clothes weren't too bad
He sat down with the man and they talked none stop, until they started getting angry
The first man began to shout at the scruffy looking one
"cosa vuoi dire che lo perso" he shouted
He was speaking a different language and I wasn't sure which one
"Non lo so" the other man shouted back
"lui è il capo della mafia, Non si capisce che vuole ucciderci" he yelled back before standing and slamming a hand on the table
"Excuse me, will you please not shout in this cafe" I asked politely
"No, shut up. We are busy" the scruffy one yelled back at me
"Leave her out of this! la nostra lite è con Stefano e la sua mafia non sua" he said back.
I didn't understand the last part of the sentence , all I knew was he said Stefano which is someone's name and mafia
Why is he talking about the mafia ?
They both left imediatly
Thank god it's almost closing time now and all the customers are gone
Bang
bang
What hell was that noise?
My curiosity got the better of me and I ran outside to see, only I wish I hadn't.....

cosa vuoi dire che lo perso = what do you mean you lost him
Non lo so= I don't know
lui è il capo della mafia, Non si capisce che vuole ucciderci= don't you understand he's head of the mafia and wants to kill us
la nostra lite è con Stefano e la sua mafia non sua= our quarrel is with Stefano and his mafia, not her
