I did the same exact thing a few weeks ago at a convenience store. She went and complained to the store manager that I was rude and slammed the door in her face.
When I explained to him, exactly what happened, he told her that he thought I was owed an apology. She went into a screaming tirade! He then threw her out of the store for upsetting his other customers.
FP—love your story.
See if the manager still has the store video of that encounter. It would look great on Youtube.
