Last week, when I was buying fruit after lunch, the hawker who is in her 40s called me “auntie” that made me so surprised.  Indeed, I’m close to 30s but I never regard myself as an “auntie”.  Maybe it’s her way to respect someone else or just her vocationally call.  I really do not mind beacause she was not trying to offend me.  I only hope the words can be used properly to avoid any misunderstanding.
