I give freelance music lessons and charge a nominal amount as am just starting out (think 13 eur an hour; am in Ireland).
One of my students always presents me with a cheque for this amount at the end of the lesson. He's a great student etc etc but aib to slightly resent the time it takes to go to bank (car drive away), deposit amount, wait to clear for 13 euro?!
i have strong hints as to why cash is preferable but all fallen on deaf ears it would seem
