A cork board tacked with roommate ads, DJ flyers, and coupons for very affordable painting classes
Those still clinging to the last vestiges of paper promotion will thumbtack layers upon layers of flyers onto a cork board that is always two sizes too small. These flyers are basically the only thing keeping print shops in business. Peel back the top layer to take a trip back in time to under-attended open mic nights, still-for-sale musical equipment, and overpriced sublets.
A very clever tip jar
Generosity comes to those who put photos from Forrest Gump on their tip jar with the caption "T.Hanks". One of a barista's most important moves is customizing their gratuity vessel to create that crucial, dollar-lubricating half-chuckle. There might be a joke scribbled in Sharpie, a collage of stickers to give off a more punk-rock vibe, or a bunch of toys glued to it to remind customers that they're probably just a bunch of kids that should be felt sorry for. However once a coffee shop reaches a certain level of polish, customization of the tip jar is looked down upon, and it is often replaced with a fancy vase or modern-looking coffee carafe.
A crumb-laden pastry case
In the early-morning hours of the coffee shop, before commuters have wiped the sleep from their eyes and pillaged every available croissant, the pastry case is a thing of beauty. Fresh scones, muffins, cookies, probably a vegan cupcake or two. But by mid-day this becomes an orphanage of crumbs, poppy seeds, and leftover muffins that are only purchased by freelance types who start to feel guilty once they hit hour four of surfing Facebook. Also worth mentioning: the mound of plastic-wrapped banana bread that seems to have never left.
