I've been interning for a small web series gig for about a year. I originally did it to get course credits, and stayed under the promise of eventual pay. There is no budget so nobody is being paid, and we use our own personal camera gear. We don't pay our locations either, we politely ask them in advance and the location owners are usually fine with it. For the final day of one particular shoot, our director told us to bring some spare change to donate to the location owners. I felt a little uncomfortable being asked this.
Is it unethical to ask your unpaid film crew to donate to the location?
