Everybody has one - a hairdresser who cuts your hair better than anyone else, a barista who makes your coffee just the way you like it, a shop assistant who is especially helpful or a restaurant that makes particularly good food.
If you already have names and faces coming to mind, then Mainstreet Wanganui needs your help.
Mainstreet is launching its annual Best of the Best poll tomorrow.
Mainstreet marketing manager, Elise Goodge, said fans of good customer service should reward the businesses they love by voting for them online or collecting a poll sheet from participating businesses.
Ms Goodge said this is the fourth year Mainstreet has run the poll.
