Almost Encountered a Robbery...

I have made it a habit to go to 7-Eleven around 1-2am to buy a drink after a nice workout.  Yesterday - while i was in the store, two black men entered and started shopping for beer.  I thought nothing of it and stood in line behind them.  Here's what happened.

One of the men stood in line to buy the beer, while the other went to the pick out another beer.  The clerk apparently spotted a gun underneath the shirt of the man that went to pick out the beer. 

Clerk: "Hey i saw what you have in your back pocket, take it out.  I have cameras all over the store"
Customer @ Counter: "Yo foo, take out your piece, he saw it"
Customer @ Isle: "What?"
Customer @ Counter: "This foo said he saw it."
Clerk: "I'm going to call the police"

The clerk begins to dial 911, and then stops as the man who was picking his beer came to the counter. 

Clerk: "Turn around and lift your shirt"

At this point i must admit i did feel my stomach whirl a bit and began to think of what i was going to do in the worst case scenario.  When the guy lifted his shirt, i saw nothing.  Could be that when he was choosing his beer and his friend called out to him, he hid the weapon somewhere else.  Anyways, the 2 black customers are now pissed, or are faking it to cover being caught.

Customer @ Counter: "What the F bitch, you calling us out cuz we're brothers? That shit ain't right man."

The clerk and the two customers share a moment of silence as they stare each other down for a while.  This was the climax, as two things could have happened.

1. The guy with the gun could pull it out and shoot the clerk out of rage.  (Even shoot me in the process because i would be a witness)
2. Pay for the beers and leave

Considering i'm alive, #2 occurred and the men proceeded to leave the store while cursing the clerk.  They were driving a black Tahoe with tinted windows.  The type of cars you'd see in movies doing drive by shootings.

I don't really think much of it - i didn't see a gun when the guy lifted his shirt and i think the clerk was just imagining things.  7-Eleven is probably not the best place to rob considering most of the large bills are locked away unlike mom-pop liquor stores.  But during those few minutes, i wasn't sure what to do.  If he did pull out a gun, and shot the clerk.. would I engaged them?  Would they have shot me too or just ran?  Who knows.. it didn't happen.

Interesting night.  If they indeed have a gun, there is a chance they will come back to try and recipricate against the clerk.  I should probably not go for a while.
