Replying to Stupid god damn shop

i took my chronics in to get mounted and i specifically told them 100 times to mount them 2cm back from center i even went into the back of the shop and measured with the guy to find out exactly where that was. So he tells me he will do it, i just got my skis back and they are mounted 6cm back from center!!
i dont really want to get them drilled again so how will they handle in the park now? will i notice the difference? will it make switch stuff harder?
