I'm not even sure if I can post on someone else's behalf, I'm relatively new to reddit, but, here goes 

My girlfriend has a 50 minute commute to the university she works at and on one particular morning, during her commute she was sat adjacent to 4 men (I assume heading to work due to them being in suits). One bloke, who will be called Mr A for ease, in particular took an interest in my GF and tried hitting on her. She politely declined and gave her reasons but this chap was persistent in his goals and tried to compare his life and work to be better than mine (despite not even knowing Me, I wasn't there)

Eventually, my GF got pretty angry and told him to "fuck off or I'll kick you in the dick" it was at this point his friends started to laugh and Mr A, I think got a little embarrassed, so as a result of his hurt pride he decided to call my GF a Slut, whore etc. Your typical r/niceguys stuff. And it was at this point his friends decided to join in. My GF is pretty ruthless so she just sat there laughing. 

Their stop came before hers and they continued to blurt out expletives while leaving the train and that was the end of the encounter... I hope.

It was at this point she noticed a wallet on the 4 recently vacated seats, she sought out the driving license and low and behold, it belonged to Mr A. She stated that there was about 90 quid in notes a little shrapnel and an assortment of cards. She took it upon herself to take the wallet and buy many McDonlads breakfast meals as she could with the cash and hand them out to hungry looking people on the street afterwards she put the wallet, with all the cards but no cash, into the nearest post box. Apparently, posties will deliver a wallet provided there was an address like there was on his driving licence.
