Thinking of changing opening hours

After 2 weeks of opening, I think our shop might need to change/adjust the opening hours.
It used to be:
Mon- Fri 11am- 8pm, Tuesday (off)
Sunday and Saturday1pm-8pm

But basically Sat and Sunday were pretty dead.
(Maybe its near the industrial area where people are not working)

So, I am thinking of changing it to:
Monday- Fri 12pm- 7pm.
For Sat and Sunday will be only for appointment customers (or it will be closed for these 2 days)

Anyway, we are close on Christmas.

so I wish all of you guys a Merry Christmas and a Happy New Year.
