All I wanted was a coke*.....drugstore encounter

* referencing the Suicidal Tendencies song

Cast:
Young woman (Black)
Older woman (White)
Cashier
Me.

I go in just to pick up a 6 pack of cokes. I see the older woman with a shopping cart (didn't know they had those at drugstores) with the young woman behind her walking down an aisle. There some chatter going on. None of my business.

As I grab the cokes I see and hear the young woman (in scrubs) say, "no I've got you. You are a f'ing racist bitch"
Back and forth with the older woman declaring herself "NOT a racist bitch". She states that someone (she got this mixed up several times) in her family is "a....he's black". They are really going at it.

I get to the register and the cashier asks how I'm doing. Me, "better than THAT" pointing my thumb over my shoulder. As I'm leaving the older woman parks the shopping cart by the front door and says "I'll buy this later" then she says to the cashier "I think she has a gun".
She then walks out, through the parking lot, and on to the sidewalk. This is suburbia, no one walks around here unless they don't drive.
