My friends and I have been discussing the tactical situation.
Two clerks + possibly a manager back in the back.
That gives you three shooters. (assuming of course they would be willing)
In that crowd its likely a 1 to 4 ratio of unarmed to “stolen pistol in the pants”
Assume 40 people in that crowd and you are looking at 10 tangos vs your 2-3 shooters.
Also they are spread throughout the store, your guys are behind the counter in one area which draws combined fire.
Except we don’t kill people over a bag of potato chips. Especially if your kid just happens to be in there getting a soda when the clerks open fire indiscriminately.
