[Druid] registration fee refund

Dear DRUID, My name is Yoon-Kyung Kim, and I am a presenter at the DRUID 2023 conference.  I am writing to inquire about the refund of the registration fee. Unfortunately, I did not know the registration fee includes dinner, so I checked the dinner option (100 euros). Since I am receiving school funding for DRUID 2023, I need to get a revised receipt as soon as possible. I would like your assistance in finding a solution for my refund.  Thank you for your attention to this matter, and I look forward to your response. Best regards,  Yoon-Kyung Kim
