Scanning items.... as well as remembering a bunch of different retail laws that could get them sacked and charged if they don't uphold them, and dealing with an irate public in a time of crisis and having to remain calm and try to de-escalate situations while being screamed at by said irate public for things that are out of the employee's hands.

It's easy to minimise how hard a job is when you're ignorant of what it entails I suppose.
