Homeless person (derogatory)

You are working as usual, with plenty of visitors; you are considered the best employee in the entire city. You invite a new client in, and as he enters, you see that he is a homeless man—a quiet and shy homeless man who reeks of garbage and urine. He is short, about ten centimeters shorter than you, and weighs less than you do; he looks to be twenty-four, and you are older than him. He seems very awkward about asking for your service, as your treatment is expensive, and he has likely never had even half that amount of money in his life. He swallows hesitantly, whispering softly H-hello... May I warm up here?

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