Gas Pump Dings
Here's another gas pump distribution. Inattentive users of the pump's nozzle have carelessly returned it to its home. In the process they have dinged the vertical panel on the left. The nozzle has its set home, but the users have sometimes started too high for its return resulting in a few dings on the upper regions of the panel. Similarly, there are a few dings on the low end of the panel. The majority of the dings are in-line with the nozzle's home. It's a distribution pattern we've seen often: few marks high, few marks low, and most marks in between.
