Is it appropriate to invite you to dinner at noon on Monday?

It is not appropriate to invite you to dinner at noon on Monday. Because first of all, Monday is the first day of work after the weekend, so it is not suitable for treating guests on this day, and secondly, it is not suitable for noon. Lunch break at noon is usually one elbow, and there is not enough time.

So it's best to invite guests to dinner on Friday night. First, there will be enough time after work. Second, we will have a rest for two days. It doesn't matter if you go back late.
