Won't accept what was requested

There's a woman who rides the TTC (Toronto transit) subway during evening rush hour, she shuffles from one end of the train to the other and back again, shoving her way through all the commuters, shouting “Please can you help me with something to eat” - that's a direct quote, she's been doing it for years and always uses that exact phrase. Keep in mind, she's not asking for money, she's not asking for cash with which to buy food - she's asking for food. On numerous occasions I have seen people offer her actual food, only for her to fly off the handle that they would do such a thing instead of giving her money.
