What is the incentive to reduce service? Service is what brings in the money. If a bar doesn't make money after 11pm, it's not a reduction in service to close at 11. You aren't serving anyone.
If a business is working at full capacity and can't pay the bills, that's one thing, but a business which could easily accommodate more customers and doesn't have them is not a viable business, if it can't cover it's expenses.
Would dropping the minimum wage saved any of these businesses? What point do we go to keep a business open? Would a crew which consisted of six family members who work full time just to cover the fixed costs be a tenable business model?
A bar makes money after 11pm. The question is if it makes enough to meet costs. The higher those costs the less likely this is to be true and the earlier it will close.
Is the bar shoulder to shoulder after 11pm? I don't think so.
But. I'll ask the question again. If the minimum wage dropped a buck, would it save the business?
