I’m not saying there isn’t, but the point is that if you’re operating a business which provides a service to the public, the task of ‘providing a service to the public’ lasts for as long as it’s posted hours.
No, it’s not a different argument. We are literally discussing shift length. Thats the topic of discussion that everyone is engaging in. You just can’t read.
The 7/11 being open is not "a person's job". That is the topic. What individual jobs entail.
And why are you still pretending that post only mentions hours?
If the 7/11 is open for 19 hours then there is, by definition, 19 hours of standing behind a cash register to be done. You can split that up every which way but there’s no way to do it faster.
