There is no such law about scheduling hours, only that they are required to pay minimum wage, how many hours you can work if a minor, or when/if you are allowed breaks/lunch and overtime.
It appears that at 7pm, McDonalds like many retail stores were short of people or needed the employees to work longer to take care of business so asked you to stay. I am sure there are days when they may call you in or others to take care of business when someone calls in sick or short of staff.
Go to the department of labor and it will list what is required or not.
