PITTSBURG, Kan. — For former Parsons resident Ronald Hicks, Pichler’s Chicken Annies is his favorite place to eat in the whole world. So, when he mistakenly gave his waitress $550 for a tip, he was grateful when she and the restaurant’s manager chased after him to return his money. Last month, Hicks, who now lives in Olathe, was visiting his hometown, Parsons, and unveiling an art exhibit in honor of the memory of his twin brother.
