The nearest actual box of gloves could very well be several minutes walk away from the gate itself, and if the captain doesn't want to wait, you just consigned yourself to missing the flight to try to get under a TSO's skin over a bag search that should take, at the most, thirty seconds, and that's if you have a stuffed-full carry-on.

And while the TSO is en route, other passengers might stop them to ask questions, or to ask for directions. The passive-aggressive and vindictive TSO could also just take their very sweet time in getting there and returning.
