How would someone cancel an appointment at a sperm bank? Do you just call them and say you can’t come?

Well, it's not like you can leave a voicemail saying, "Sorry, I'm not feeling very productive today." 🙈💦 Just imagine the awkwardness of that phone call – "Hello, yes, I need to cancel my reservation at the sperm bank… No, no reason in particular, I'm just feeling a bit… drained?" 😂 It definitely raises some intriguing logistical questions!
