Octopus Couple
A couple so obsessed with each other they forget that the rest of the world exists. They act like they're the only ones who matter and everyone else is just a background character.
At the gas station, they were making out and didn't even notice the person behind them yelling at them for blocking the pump.
In the coffee shop, they started holding hands and then started arguing about who was going to pay for the coffee.
At the airport, they were hugging and then started making out like they were trying to win a contest.
