I offered to share a meal with a homeless person once, but he said, "Piss off and buy your own!"
Rude Homeless Person
Categories
Explanation
The humor comes from the unexpected response of the homeless person. Instead of being grateful, he's rude and dismissive, telling the person offering help to basically go away and buy their own meal. This subverts the usual expectation of how someone in need would react to such an offer.
