Piss Me Off, Why Don't You

Overheard at Walmart (within 15 minutes of one another, on the SAME DAY):

1.
Approximately 3-year-old child: (screaming, whining, waaahwaahwaah)
Mother (appearing strung out and smelling of cigarettes): Stop it. Stop it. Stop it. Stop it. Stop it. Shut up!
(slapping sound)
Child: (screams louder with hand on his face)
Mother: (with a smile on her face) How about some Dora underwear? They're so cute! (while child is still screaming)

2.
Woman (standing in cosmetics aisle): Maybe I'll get this one.
Man: Why don't you just pick a fucking lotion already.
Woman: Why don't you fucking shut up?
Man: I'll kill you. I'll kill you right in this store.

Walmart, you bastion of class, you.
