Mexico doesn’t “celebrate” the 5th of May. It is not an official holiday there. Even if it were, I don’t live in Mexico to begin with.
So.
I don’t give a rip.
as a bartender, i don’t give a rip what the “holiday” commemerates. if it means more people come into my bar and tip me, then i’ll put up the corona signs, the pinatas, the inflatable sombreros, wear the little blinkie buttons.. whatever.
