history: My mom yelled at a cashier and i felt like i should have left her there. The other day my mom yelled at a cashier. She was so unreasonable. Why was she yelling at the cashier? She thought the cashier was charging her extra. I feel a little bad for the cashier. Same here. They already have a tough job dealing with so many people.
current: I agree. So many people are inconsiderate of workers.
next: I have worked jobs like that so i always make sure to make my interaction with them as pleasant as possible.
