<human>: TIFU AT WORK

I work in a grocery store and I was serving my boss. She said that she was in a hurry because she seen a delivery truck arriving. Incase your wondering she wanted to get into her car before the truck blocked the exit. (the car park is tiny)
   She was about to leave but remembered that she needed batteries. She was digging through her bag very quickly to get her money. Then I made a comment "I never seen you move so quickly" she let out a loud gasp and paid me before leaving. 
   I had no idea what offended her until I explained my story to a co worker and they made it clear. 
   I'm in tomorrow and I'm not looking forward to it.

Give me a shortened version of the text
