Besides diligently producing ice, what has your ice maker done for you lately? For one store owner in Little Rock, the ice maker saved the day (emphasis mine):
According to a report, responding officers found a large hole in a wall on the west side of Expressmart at 1501 W. Roosevelt Road shortly before 3 a.m. Authorities said it did not appear anyone was able to enter the business, and later determined through surveillance footage that the burglars were stopped by an ice maker in the way and fled in a northwest direction. (Arkansas Democrat Gazette, October 5, 2016)
The details of the story may show that the burglars were stopped by there simply being something in the way, but you could say a lot of heroes start out simply being in the right place at the right time.
