What is the unwritten rule for reimbursement among friends?
If you ask a friend to purchase something on your behalf with a promise to pay them back, you are legally and socially obligated to settle that debt as soon as they deliver the item, regardless of whether the specific brand or style perfectly matches your preferences.
How can friends resolve a petty financial argument over an errand?
