Would you think guys using a womans need to survive as unethical?

If there was a very attractive and young female homeless gal (maybe a runaway years before) who lived in or near your neighborhood and it was well known for a little bit of food (even as little as a value menu hamburger) she can be had for any type of sex asked, what would you think of guys who would take her up on it with cheap food like a single burrito, kid’s sized burger, cup of yogurt etc? What would you do if she refused a decent meal (for free, no favors asked) out of pride to not seem like a down and out person in need of rescue and feel she has to give something in order not to be a charity case?
