I do find it interesting that some cafes (and it happened to me recently in Adelaide) that you go in at 3.05 and they say no the kitchen closes at 3pm. I wonder if it's the employees who just want to get out of there and if it was the owners they could think - here's another $30 or $40 I can do that.
Well it's always down to the owners. They're probably only paying the employees to a specific time who then have a few hours off until dinner time. With tenuous employment, and wage theft rife there is no benefit for employees to donate more time to one of their employers.
