Guess what just happened? Again.

Guess what just happened? Again. So, my friend and I went to go see Spider-Man: Far From Home today. This time, I had money so I was going to get us drinks. We bought wanted rootbeer. So I go up to the cashier and say "can i have 2 small r..." And I can't get it out. Finally, I'm able to get it, and the cashier goes "pardon?" So I have to say it again, and this time I stutter on two and have an even harder time saying rootbeer. And there's this huge line of people behind me and I felt so awkward because I heard someone say what's the holdup, and that kind of brought down my mood for the movie. Do you guys connect to me here?
