I (F21) work at a café where there's only one person helping customers at a time so we can't leave until the person on the next shift shows up.

So one day, I was planning to spend the day with my dad after work. He told me he would pick me up from my job when I got off at 4. My dad arrived at 4 and waited inside the café for me to be able to clock out. I had everything ready to leave but my coworker was nowhere to be seen. I had to keep helping customers while telling my dad I'd be ready to go any minute.

Well, at around 4:18, a woman and her daughter walked in and the daughter ordered a tea. I started making it and, halfway through, that's when my coworker showed up. I told my coworker the order so she could finish making it and clocked out and was rushing to leave with my dad when the woman who's daughter ordered the tea stopped me at the door and asked, "Are you going to finish our order?"

I said, "My co-worker will finish it."

She said, "Well she isn't making it."

I looked over at my co-worker and she was cashing into the system which I admit would delay the drink a bit and I hadn't thought about that but I was already 20 minutes late getting out the door so I was rushing and not thinking.

I looked back and forth between her and my dad feeling super stressed and then said, "I'm sorry. I was supposed to be off work 20 minutes ago. Do you want me to go finish it?"

She said, "Yes."

And then her daughter, the one who ordered the tea, spoke up and said, "No, you're fine. Go."

I thanked her and left.

I'm worried I was in the wrong for throwing that drink on my co-worker when it was going to cause a delay in the customer receiving it and that woman seemed really upset.
