Full laser or Spot treatments ???

Hi everyone, this is a fantastic forum!!

My question is, ive just started diode lightsheer laser treatments on my chin and neck. Ive had 2 treatments so far and each time the nurse only does sections of the area instead of the WHOLE area. Is this right? Since im paying $220 australian for each session, id assume i would be getting FULL treatments instead of just SPOT treatments. Has anyone else experienced this? Or am i being ripped off? :confused:
