At least you get a warning....
The Bat and my boys will SBD right next to you in the store aisle and send you running with your shopping cart to get out of the cloud of fumes, all the while praying that no one else in that aisle thought it was you. They then look at you like a deer in the headlights and say, quite innocently, "What? I don't smell anything!" and laugh as you flee in the other direction.
As you pass that aisle later to go to the register, you can see that it is still a deserted and barren wasteland with the labels peeling off the jars and littering the floor, and black skid marks from all the shopping carts that had burned rubber to get away from the toxic area. You'll remember the aisle because on either end will be orange cones with a biohazard logo on them....
Really, words cannot describe the carnage left in the wake of one of these bombs.
