I Half Hate This Job, And Hate Half This Job

(I am working a trial shift as part of my application to work at a fast food restaurant. I am unfamiliar with the menu and a little flustered.)

Customer: “I want a frozen drink.”

Me: “Sure! Which flavour would you like?”

Customer: “A frozen drink.”

Me: “Yes, I got that, but which one?”

Customer: “It’s a dollar.”

Me: “Okay, but—”

(My coworker notices my problem and steps over to help.) 

Coworker: “Hi there, ma’am. Sorry about this, [My Name] is only new and just learning how to take orders. Did you want the cola flavour or the green one?”

Customer: “YOU KNOW WHAT I WANT!”

Coworker: “I’m sorry, I don’t. I’m asking you.”

Customer: “YOU ALREADY KNOW! I HAVEN’T DECIDED! YOU KNOW WHAT I WANT!”

Coworker: *pause* “Would you like it half of each?”

Customer: “YES! WAS THAT SO HARD? IF YOU KNEW WHAT I WANTED WHY DIDN’T YOU JUST DO IT?”

(Later:)

Coworker: “Sorry about that. I’d say that doesn’t happen often, but you probably should get used to it.”

Me: “I hate this job.”
