Rules
Restaurants seem to have their ‘rules’ as to when a particular meal can be served. Some, when anything can be served.
I recall one which served breakfast from 8 am to 10 am then closed to set up for lunch. If you walked in after 10 you couldn’t get anything.
That restaurant, is, of course, no longer in existence.
Others set their times; 7 to 11 is breakfast, lunch is 11 to 3 and dinner is 3 to 7.
Again, these ‘rules’ assist in going out of business.
Although I am discussing a restaurant, you can easily translate this into any business which has unnecessary rules.
