When I was in the grocery business, a man did the same thing using grapes in the "wine corner". His wife wanted me to help him up off the floor. Instead, I ran across the street to the EMS station. One of the EMS guys told me it was a good thing I did not help him up as the couple made a living off of the slip and fall routine. Our company settled with them.
On a subsequent visit I caught them shoplifting. Low lives.
Months later, we rode a hospital elevator together (not by choice). No sightings since then, thank goodness.
