I say right away, my personal opinion.
In the layouts of our time, closing for lunch is a controversial issue!
Many people work without lunch and seven days a week. And here, you come and have to wait until the "gentlemen" have lunch ....
There is no respect for the client in this. Again, my opinion is that you should value someone else's time! And if someone breaks away from eating once, then it won't be a big deal.
