In my store that will get your shit dumped on the floor.. SFS only.. Cause they did that and took carts that were full waiting to be packed, and we lost batches and had to cancel orders. Yeah that is a "oh fuck no!" The rule we put in since we don't actually use all the SFS carts we have was we didn't label all of them, so the ones that are blank are up for grabs for any team that needs it. But if its labeled? yeah just don't do it.
Our response is always, not our responsibility to make up for your mistakes. You can make empty vehicles just as easily as taking ours.
