This is totally up to you. When the DJ meets or exceeds your expectations any tips would be his. We do not ask for any of the tip. We ask them to report it. That way we know they did a great job. They are compensated at the end of the year with a bonus based on feedback so we would really like you to fill in the questionaire we will send you after the event.
A hug is just as much appreciated and additional referals.
