A Wichita man who feeds the homeless has learned it takes a permit to spread goodwill.

David Hill has been serving hot food every third Saturday for the past two years. The Wichita Eagle reported that he figures he feeds about 300 people per month.

It wasn’t until this fall that an officer asked to see his food safety permit. Hill says he didn’t know he needed one.

Hill has gotten a temporary permit and plans to meet with someone from the city.

Officials say the permit requirement exists to make sure the needy are fed safely.

Hill operates his program through One Spark. The effort started in Wichita and has built a following by encouraging people to pass on what Hill calls “random acts of kindness.”
