Homeless person (derogatory)

You're working as usual, you have many clients, you're considered the best employee in the whole city. You invite a new client in, and when he enters, you see that he's a homeless man, a quiet and shy homeless man, he smells of garbage and urine. He's short, about ten centimeters shorter than you, and weighs less than you; he looks about twenty-four, you're older than him. He seems very uncomfortable asking for your services, as your treatment is expensive, and he's never had even half that amount of money in his life. He hesitantly swallows, whispering quietly, H-hello... May I warm up here?

You've been working for many years when one day an unexpected visitor arrives.
