Buy yourself a nice drink :). Starbucks makes everything better ;)
Grab a plastic cup big enough to hold your drink. (Please ignore the messy car and random foot)
Place cup in the pocket inside the seat in front of you. (Consequently, if your car does not have seat pockets, this will not work. However, I could do a guide on how to make car pockets....hmm)
Then put you fancy Starbucks drink into your cup which is in your pocket. In case you were wondering, the drink is a skinny mocha frappe with soy. But you weren't, were you.
Thanks for viewing my guide! I know it was simple and a little useless, but I was bored. It is kinda helpful though, you gotta admit. Enjoy!
