Whenever both of us inflict pain to each other, we'd just laugh it off and be friends again, or just go eat. Sometimes the 'inflicting pain to each other process' can earn some profanities from both of our mouths but both of us are good. So... Yes I would definitely slap my friend.
Not because I'm money-hungry nor I'm desperate for money. At least I can treat my friend to foods and help support my family - I would literally never waste my money on something idiotic.
