Potentially. In order to succeed on a slip and fall accident claim against a store or restaurant when your accident was caused by a liquid or other substance spilled by a customer, you will need to prove that the store or restaurant knew of the spill or that the spill had been there long enough that the store or restaurant should have discovered the spill, and that the store or restaurant had enough opportunity to clean up the spill. If you slip only a minute or two after another customer spills a liquid on the floor, the store or restaurant can argue that it did not have notice of the spill or sufficient opportunity to clean it up.
