Are you working for a non-profit? Do you earn any money because of this work? Do you buy fairtrade coffee? Do you encourage volunteers to work for your non-profit organization so you can continue to have your income? Are they aware of helping you OR they think they just help a good cause? Are they wealthy philantropists? Are they by any chance just simple local folks vulnerable in a sense that they have difficulty saying “no” or not thinking deep enough? Warning: this may not be about your case.
