Tipping culture is definitely still a huge issue for servers in the US. While, for other countries, tips are encouraged but not needed, they help servers, bartenders, and other service workers make a living wage. Though it definitely isn't ideal, many servers rely heavily on tips, meaning that it's important for restaurant and bar-goers to tip when they can.
Back in 2020, a TikToker named Aaliyah Cortez (@f.aa.ded) posted a viral vid showing the importance of tipping. The TikToker, who was working as a bartender at the time, showed just how little she made with her regular wage after deductions.
