Open at 14 o'clock

The number of guests is fine but it is narrow. People who are male-only are likely to feel narrower. After that, please be careful when entering the store.

The head office was listed on the web at 14 o'clock opening.

Certainly it shouldn't be done too late. Even if you put in at 11 o'clock at night, it may be released immediately. You should check the business hours before going.
