Frankly, whether or not you're carrying someone else's money and/or have a gun is irrelevant. It may be relevant to you, but someone else's money and your gun not being delayed 3 seconds is not relevant to me. Someone else's money can wait 3 seconds if I want to get the the grapefruits in the supermarket. Those aims are not more important than mine - which I will value, at the moment, to the exact amount you are carrying.
If someone is deliberately obstructing you, that's different. Again, the money and the gun are irrelevant. Obsruction of another person is rude, and rudeness is an acceptable response.
But your money and your gun have nothing to do with it. They are not more important than my grapefruit.
