My laptop costs me $3,500 and I buy one every four years. It’s a huge investment. For that reason, I’m insanely careful about when I have it out.
My gut reaction is that the company whose employee damaged your laptop should pay for it. But I also understand why they decided to pass that risk to the customer to keep ticket prices affordable.
I would let this one go. It’s an Air - not a Pro - and the cost to repair or replace is likely not high enough to make it worth fighting them in court.
Call it a tough lesson learned and tell your kids about it. Sometimes these expensive lessons pay for themselves if they help you teach your kids about responsibility.
Hate that you’re dealing with this, OP. It sucks.
