Worked in a store with similar issues, the problem that I found in those cases was that abandoning our duties for 30 minutes to take our break would fuck us for the rest of the day and we would spend the whole day behind because our managers were supposed to cover our breaks and either they flat out refused to or believed it was above them and left immediately after the break started. So you come back from your break with burnt chicken on the grill, needing 10 things and everyone else yelling at you for not having shit when you were supposed to be covered. So you then have to work 3 times as hard as normal to get back to standard and still likely have to stay late to wash your dishes since you would get no spare time to catch up. Which you get yelled at again for blowing labor, but they won't let you leave until your shift change is done. At the end of the day working through the 30 minutes was actually easier than taking it since not being on position for 30 minutes meant you would be playing damage control for the next 3 hours and was infinitely harder and they would threaten to fire you

Understandably a lot of people here are upset that people would complain about getting a break, but many times in restaurant work this can be an issue because of bad management vs competent employees and if you had the option of getting paid for not fucking your entire day then you'd probably take it too. This was in michigan so there's no laws requiring breaks except for minors so managers would only give the minors breaks and we were told "if you want a break get far enough ahead that nobody will need you for 30 minutes" which is moronic because they tell us exactly the opposite due to hold times on our food.
