"You never know who may be listening to you..." --Paul McCartney
Some of my best future opportunities came from someone who happened to saunter in for a cold one and was impressed with what they saw/heard.
I am in that camp of weirdos who feel every audience deserves your best, the full show, best gear, best aesthetic, best performance, regardless of the prevailing socio-economic demographics. Indeed, when I'm in a real crap-hole I love the look of surprise and delight on the faces of patrons who weren't expecting anything near the level of professionalism and entertainment my band provides. It certainly helps them justify the 500% mark-up on their beverage.
Class up the place. Prepare for fate. Bring your best. Always.
