A convenience store chain was sued by a customer who slipped and fell at the front door. An ongoing snow storm made conditions hazardous.  Recognizing this, the store employees posted signs on the doors warning of slippery conditions, and repeatedly running floor cleaning equipment through the store. But the plaintiff—attired in short and flip-flops—fell and break his ankle. A jury in Tulsa County District Court found that the store employees went above and beyond the call of duty in dealing with the dangerous weather. Partner Nathan Clark countered the plaintiff’s simple claim—I fell, it was wet, it was not my job to keep it dry—by showing the floor safety procedures by store management and how its employees followed and documented the procedures.
