"I just want to know: when I spend ₺300 at dinner, how many of MY dollars was that?"
"After every trip I spend 2 hours in Google Sheets. It's killing the post-trip vibe."
"I withdraw small amounts because within days it's worth less. I need my real burn rate."
"We Venmo each other randomly and nobody knows who owes what anymore."
"I lent her money in lira but the lira keeps dropping. Am I even getting paid back?"
