It can Be Assumed That Everyone was Angry
This narrative had the potential to go in a great number of different directions. It had the makings of a good comedy, with the protagonist desperately trying to keep his date occupied while his ex-girlfriend hurls insults at him. An ex-girlfriend may do everything in her power to not only ruin the date but also make the guy appear to be as unattractive as possible.
In any case, you can be certain that the details in her stories have been exaggerated to some degree. This may seem like a good idea for a story, but the individual in question was most likely experiencing a great deal of discomfort at the time. We really hope that this guy got the message that he needed to tip the waitress a little bit more if things didn’t turn out too badly.
