Cash or Transfer?

This is an expression used by most Uber drivers in Nigeria when they pick up a new request by phone call or when the passenger approaches the door. They usually want to verify how they will be paid since many of them need cash instantly and Uber remits the drivers after a few days when the passenger pays with the card on the app.

It is also used when you want to humorously or indirectly ask someone to pay for a service or a favour. By asking "Cash or Transfer?" You are going straight to asking the person how they would prefer to pay, skipping the part where you tell them that they would be charged for the service.

You can also use it to ask a person how they prefer to be paid or sent money (in the case of gifts).

Peter: John, my laptop cable is bad again, can I borrow yours, please?
John: Cash or Transfer?
Peter: John, you're crazy 😂😂😂

Stephanie: Hello Sir, I'm your rider to Beverly Hills
Uber Driver: Cash or Transfer?

Gardener: I have finished the job, I'm ready to leave
Child: Ok, I'll tell my mum, she's the one who would pay you.
Gardener: Cash or transfer? Because I don't want bank issues or delay, plus they always take bank charges and my payment received will be incomplete.
Child: So, you would prefer cash. I'll tell my mum.
