For context - my friend works in a supermarket, and said, people fiddle the self service checkouts all the time, by putting in cheap veg instead of expensive ones.

Are these people reported for shoplifting?

He also mentioned skip scanning, are these people commonly reported for shoplifting, or are they treated as forgetting to scan?
