Sometimes you have too much work to do and in order to move fast, you cut corners. You get a couple thousand shirts at the dock, you don’t feel like you have time to count it and then the customer picks it up before you get your final counts. Now the customer gets back to you and tells you they are missing a ton of shirts, but you have no record of what came in and what went out.
Slow down Follow your own processes. Don’t lose money over stupid stuff. We miscounted 1,500 out of a 15,000 shirts and have no way to prove whether we printed them or not.
