The cashier
When will people learn that unless it’s super obvious that there is a strong connection with someone, do not go out of your way to ask them out? Especially do not break that rule if you are an employee somewhere and you ask out a customer. Just ask this guy, he lost his job as a result.
The cashier thought this girl named Rachel was very cute and decided to find her number and message her later that day. Rachel immediately reported this to his workplace and he has fired right after. He should have known better and realized what he was doing was very creepy. For all, she knows he could have been a psychopath.
