A cute regular customer lol

It was a day I was working alone because the other part-timer didn't show up.
I was so busy that I only managed to take this person's order call and missed the calls that came in after that.
Once the rush was over, I saw a few missed calls, so I tried calling back, but they didn't pick up.
When they finally came in, they were so incredibly angry...
Even when I said, "I'm so sorry, I was too busy to pick up the phone," they still lost it on me...
I thought they weren't coming back anymore, but then a few days later, they showed up with a smile and ordered 5 items lol
I am your loyal servant!!! Since then, I've basically been glued to the phone...
