I bet you're wondering why there is a post on manners at an ice cream store...Yes it's totally odd. But, I (C) was at a local frozen yogurt place last week and was appalled at people's behavior.
2. Be ready to order if it's crowded. If you're amongst dozens of other people at Maggie Moos, it can be annoying to others if you're contemplating between cookie dough or oreo ice cream with a line out the door! (same goes at Froyo places! move as quick as possible!)
3. Don't take up extra chairs. Seating is prime on a hot summer night!
4. Clean up all cones/spoons/napkins/bowls. Obviously.
5. Smile and say thank you! No surprise we end on this note!
