I think Sara was rude to expect him to pay for her dinner. The plans were explicitly (as in what they actually said rather than what Sara expected) for drinks. Jon let her know he had already eaten, but accompanied her somewhere where she could get food. For Sara to just sit there hinting at him to pick up the check was really off in my opinion.
I couldn't agree more. Why would Sara expect dinner when their plans were to have drinks and play games at her house? It was her house after all, if she wanted to eat she could have.
Sara believes that a date is dinner + whatever hangout plans they made. She thought the dinner was an unspoken given.
Sara is sadly mistaken, and pretty rude, to boot. Poor Jon. He thought he was having a nice, low-key date and instead got demeaned for not reading Sara's mind. If I invite someone out for drinks and video games, I mean drinks and video games. Also, to be perfectly frank, even if he had
invited her to dinner, and even if he had
intended to pick up the tab for her, it was really crass for her to ask him "aren't you going to pay for this?"
