Hey girls, bit of a silly question but how do you pay for your pics at the ultrasound scan? I assumed you just hand the sonographer the money and he/she prints out the pics, but I overheard some ladies in Mamas and Papas talking about a coin machine or something. I take it that also means I'll need loose change rather than notes? There's no mention of any of this in the appt letter. I feel like such a numpty not knowing such a basic thing lol.
