"I wasn't that upset." A rather pointed bite of pancake, even though it's mostly a cover. Maybe she was a bit more frantic than she wants to let on. She uses her napkin to cover her mouth while she talks and it becomes fairly obvious that they're the most polite people to ever grace this diner. They should feel proud. "I wanted to make sure you weren't upset. Wouldn't want to be rude."

See? Look at those aforementioned manners.
