What questions should I ask a store employee if I slip andfall on their property?

An admission by the store employee is often the strongest evidence you can gather in a premises liability, slip and fall case. If you are physically able, ask the employee about the condition that caused you to fall.  Ask them if they knew the condition existed, or when the last time that they checked the area was. It is unlikely that they will accept fault for your accident, but it never hurts to ask.
