"I didn't go there to stick my nose in someone's business"
but you did !
just think of this....that poor old sod has for what ever reason been made homeless, all he has is a tent, he might be trying to hold down a job but it's hard living as he does, some how on Monday morning he has to try and make himself presentable enough to go to work, maybe showering in the local swimming baths, maybe at a hostel or something, it's difficult but so far he's managed to hold it together, maybe moving every week or so to try and stay out of trouble with the authorities or the neds. He has no transport so he has to stay local for work / family / friends.
and then some interfering snot nosed young bloke with a strange accent turns up and tries to do good ! ...... "You can't stay here mate, oh no, it's not allowed you know, best you move on mate for your own good. "
you were lucky not to get a punch in the face and told to "F" off because by god you deserved it !
