I got quite requests a few by repeatedly loading the game up. Usually when the game loads, there's always a villager who'll ping right away. I filled my pockets up with flowers and just kept loading up and ran around to get a ping (or ran to a specific villager who I hoped would give me a certain pwp). Often the ping would be about a PWP. If the ping wasn't about a PWP I quit without saving and tried again.
I've wondered if there's a reason people swim out to sea for 5 minutes instead of restarting, because this method seems to take a lot less time.
save and continue, or go to main street
