All Happy Mask Shop buyer locations in Zelda Ocarina of Time

The Legend of Zelda: Ocarina of Time remake's Happy Mask Shop quest sends you around Hyrule peddling masks to specific customers. That sounds like a cushy gig, except you have very little guidance about who your customers are, and you occasionally even have to pay back the cost of the mask, too. However, if you want a big chunk of cash and a chance to see and hear everything in Ocarina of Time, it's worth the hassle.
