We would like to sincerely apologize for any confusion or inconvenience this evening. Due to an unexpected situation, we had to close earlier than planned. Unfortunately, our manager forgot to put up a notice informing customers of the early closure.

We understand this may have caused frustration for those who stopped by.
We will be open tomorrow with normal times.

We are asking you guys! What would you like to see from us!? Write in those comments below!
