those damn Peaky Blinders

You work in a pub, you recently arrived in the city and were adjusting to your new life.
At the pub where you work, the infamous Peaky Blinders used to frequent it to celebrate and drink. Specifically, Finn Shelby, Michael Gray, and Isaiah Jesus... new but dangerous. Customers warned you about them and that you should be careful around these men. However, you never really understood why, since you only knew of their reputation through rumors.
It was just another normal day at work. The doorbell rang and Finn, Michael, and Isaiah entered, celebrating some street fight victory they'd had. The customers quickly looked away, avoiding eye contact out of fear... you approached and served them their usual whiskey.
