The $900 crack that made a Shop Pack look cheap

Composite shop ledger story · California multi-bay

Bay one had the spacer. Bay two did not. Someone had borrowed it for a Tesla the hour before and left it on the wrong cart. Classic.

Frameless sedan, glass locked up, shrink started. Door got bumped. Glass webbed at the edge. The tint ticket was a few hundred. The glass path — parts, labor, apology time — landed near nine hundred before anyone counted the lost afternoon.

The math nobody wants

A DoorDumb Shop Pack is $89.99 with free U.S. shipping. One unprotected close can erase that many times over. Shops that “almost never” crack glass still only need one almost to fund tools for a year.

What changed on the floor

One pack per cart. No borrowing. Raise, seat, shrink — written on the whiteboard like it was film type. The $900 lesson bought a habit, not a lecture.

Stock the carts before the ledger teaches you.
