I don't know how true this is- but I've tried it, and it has worked for me every time except 1 or 2. By worked, I mean it has caused my villagers to get the exclamation and run to talk to me. I haven't had public works requested due to this.. YET)
Put on the wet suit and go into the water. Purposely get stung by a jellyfish, and swim around for a few minutes, staying out of site from your villagers and diving for deep sea creatures. Then slowly approach each villager from the angle they are facing. Usually at least 1 of them will say *something*.
I have no idea why that works but eh.
I have had three requests so far:
1) Yield sign
2) Caution sign
3) Traffic signal
WHY VILLAGERS? WHY DO YOU WANT THESE AWFUL THINGS?
PLEASE REQUEST A FAIRY TALE BRIDGE INSTEAD OR A POLICE STATION OR INSTRUMENT CENTER OR SOMETHING GOOD
I am also quite anxious to do the train station remodel, unlocking that will take forever
IT WORKED O.O!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I got a caution sign but at least it's something new, dude thanks!
