I'm pretty sure that's a Royal Mail van in the background, so it must be in the UK somewhere.
It's definitely Scotland, and the Facebook page it's taken from is a clergyman in Greenock (west of Glasgow), but another poster said they thought the brother might be from Stevenson congregation though. Either way, it's still definitely Scotland.
And the guy on the right isn't wearing a "hoodie", it's just a windbreaker style jacket - highly nescessary in cold Scotland!
I actually did not think it was a beggar but another coffee drinker taking it easy, having a rest.
I'm pretty sure that's not the case - he's almost sat cross-legged on a bit of something to give him comfort, and in a major pedestrian throughfare where he will get noticed. If it's a town center or a town square, there will almost certainly be much comfier places nearby to sit than there, but wouldn't get you noticed.
