Night Work (1930)

As assistant window-dresser, Willie is the lowest man on the totem pole at a department store. To add insult to injury, he is also the store's designated "Fired Man": when a disgruntled customer demands that somebody-must-be-fired, Willie is summoned and summarily fired, only to be rehired when the now-satisfied customer has departed. Willie inadvertently adopts a 4-year-old orphan at a cost of $10-a-week, and things go from bad to worse since Willie doesn't make $10-a-wee. But with the help of beautiful young nurse Mary, Willie manages to turn some corners and improve his lot in life--with some skids along the way.
