Usually, toddlers have the monopoly on sugar-related hissy fits. But fully grown adults gave them a run for their money during this week’s Unicorn Frappuccino hysteria.

Starbucks employees are still reeling from what many described as their worst day on the job, after hoards of customers demanded the color-changing beverage with 76 grams of sugar.

Supplies ran out, tempers ran high and an evil side of humanity was on full display. One barista posted on Reddit, “Honestly, the number of grown-ass human beings throwing temper tantrums was disgusting. You’re grown, get a hobby.” Another recalled how “a grown woman screamed when we told her we don’t have any more.”

Yet another barista explained how, after telling an actual fully formed man that there were no Unicorn Frappuccinos left, the man “told me to ‘get lost’ over the speaker, then proceeded to do a poorly executed burnout in my drive-thru right beside a car full of friendly teenagers that were not upset over us not having the Unicorn Frappuccino, and instead ordered reasonable drinks.”

One poor intern reported being sent out for coffee by her boss and getting an order of seven Unicorn Frappuccinos. Because nothing says authority quite like whipped cream that has been sprinkled with pink and blue fairy powders.

It’s not exactly surprising that coveters of mythical-creature-themed Frappuccinos might be lacking in the maturity department. But if you think being denied said frapp warrants a full-on temper tantrum, it’s time for a good, hard look in the mirror.

Unicorn Frappuccinos are not some kind of treat for “adulting.” They are 11 grams of saturated fat and an infantile escape from reality.

Also, they don’t even have coffee in them.
