I think you would have a problem by alienating almost all women and most married men. I can't think of a woman who would support it. You must have some REALLY good Coffee. Here are some statistics:

Lets pretend 50% of potential customers are female and 50% of the remaining male population are married. That leaves you with a potential 25% of your remaining population.

Of which.. maybe... maybe 1-2% will shop at your store.

Can your business survive on 3 visits per day at $.50-$3.00 profit per purchase? That's profit before rent, lights, labor, etc..
