I worked with Lonnie in Hutchinson, Kansas at Dillon’s Food Stores when we were both teenagers. We were good friends and went our separate ways to pursue our careers. He went to New York and I went to Texas. I retired on Friday and thought about Lonnie only to find out he passed. I wish his family the best and I wish we could see each other at this point in life. Rest in peace friend.
