1. The "I still need help from my parents to not go broke" payment.
Whether it's for textbooks, groceries, or the typical obscure "don't spend this on alcohol" payment, most college students are probably still getting some help from their parents.
2. The 5 part Uber split.
Sometimes people forget to fare split the Uber or Lyft before it's too late. Other times, you forget that's a thing. Either way you've probably charged five of your friends $0.87 for "Uber" at some point.
3. The "charge your roommate for everything you've bought in the past month" transaction.
When you have to list your transactions as "1/2 paper towels, 1/4 groceries, 1/2 lightbulbs," your life can start to feel more like an accounting class than an easy way to pay friends.
4. The "I don't want to specify that this is for alcohol but it's for alcohol" payment.
Insert obscure emoji or "u know" caption, but in reality everyone knows.
