Replying to Waiver to get skis mounted???

ok well today i went to a ski shop around me with a friend because he wanted to get his fugis center mounted and retuned. and the clerk asked if he had a parent present. he said no. Im guessing because he was getting them center mounted that it was a liability kind of thing. do any of your shops do this? i plan on getting my chronics center mounted tomorrow and when i get a new pair of skis in like a month i plan to get them mounted too. if they ask im just going to say ive been skiing for 7 years and i bought the skis. also my mom doesnt know anything about skiing by the way so she wouldnt even know why she would need to sign something.
