Clock in Clock out
Zone in Zone out

New tables, same worries
Same tables,  new stories
Each day begins
Clock in again
New friends same places
Same names new faces
No one sees sun
Clock out days done
Same ways new worries 
New ways same stories

Zone in zone out
Clock in Clock out

This is quite brilliant. Captures the essence of a retail / service job without being gimmicky.
More please.
