The Cashier at Walmart!
I was buying yellow roses for my mom on Valentines day and needed a second opinion.
I hand the cashier the roses.
Me: If you bought these for your mom would she like them?
Cashier: (looks at the flowers) Well they are flowers but what color are they?
Me: *sarcasticlly says* they're blue!
Cashier: (looks at me with serious face)Ma'am, I am color blind.
I am such a bitch.
