Well, by offering food for punch in the face you changed it from charity to free market transaction. Basically you gave them a chance to earn their food instead of just giving it to them. If they deem the price too high and refuse your offer then again, nothing bad happened.

Not all free market transactions are reasonable. Selling yourself into slavery is a "free market transaction" I hope you would not consider legitimate.

Being offered something unreasonable, given free reign to decline that offer, does not cause harm.
