When you pay someone back, are you rounding up or rounding down?

@JackHoff I feel like I’m paying someone or they’re paying me once or twice a week. Today someone asked if I could get them a bottle of water and they’d Venmo me. I said to not worry about it, I’ll just get the water. They insisted they send the money, so I said ok, and then they rounded down. It didn’t bother me, I didn’t even want them to pay, but I’m always an exact change or round up person.

@itsok that was nice of you and I would rather them not pay me then round down.
