Looks Can Be Deceiving
You’ve emptied your shopping basket onto the conveyor belt. You watch your eggs, milk, and cheese slide over to the cute cashier who greets you with a beaming smile. She asks about your day and tells you to enjoy the rest of your weekend. She’s totally into you, right? Right?
Probably not. You might have been ready to change your Facebook relationship status the second you saw her, but she was just doing her job by being friendly and approachable. Had she not been smiling, we guarantee someone would have told her she should smile more. We can never win.
