That A&W at the Naha Airport

Hello Okinawa!
It’s been awhile
this prefecture I was born in
and yet know almost nothing about.
While waiting for the rest of the family to land from Osaka
I was drinking a root beer float at A&W.
At the counter they mentioned
that there are free refills for all the drinks.
It felt very Okinawan.
Or at least definitely foreign.
Hoping I can reconnect with this motherland of mine.
