Speaking of saps

I was in a liquor store in the midwest today. Beer distributor is talking to the cashier, they're bitching about the economy, complaining about their sales. Beer guy asks the cashier if there's a lot Mexicans in the area. Yea, she says in a nasty tone of voice, they're fucking everywhere. You can always tell, says the beer guy as he sadly shakes his head. God damn Corona's flying off the shelves. Motherfuckers are like cockroaches, or some similar sentiment, hangs in the air, unsaid.

There are important lessons in that exchange, somewhere.
