I don't think the nightlife scene would end a a catastrophic drain. It's up to the owner if they want to embed in resourcing out their club or bar. Organization is big when you own a business of value. Clubs that are open every night without the correct structure would be looked at as a joy spot instead of respected establishment. Those who give their business time to build an atmosphere for itself or the people involved will see more value to their ownership and employees. I'd say give it a week to get ready for the establishment's opening date, it'd help on both ends: for the employees and crowd.
Spending a week isn't too bad, when the points are to grasps the attention of the server's immersion. The mentality most businesses should have is that; the plan. Advertisements can play a part, but word to mouth keeps control, concept, and continuation.
