A Woman Made Fun of My 83-Year-Old Mom at Checkout – Then the Cashier Locked Her Register and Said, ‘Nobody Leaves’

I thought the worst part of that grocery trip would be watching a stranger humiliate my 83-year-old mother for taking too long at the checkout. Then the cashier looked at Mom’s face, went pale, locked her register, and called for a box she’d been keeping in the back office for seven months.
My 83-year-old mother still insisted on doing her own grocery shopping.
That Saturday, the store was packed.
Mom had only six items, but when it was her turn to pay, she struggled to find her wallet.
The woman behind us sighed loudly.
“Oh, come on.”
Mom glanced back.
“I’m sorry.”
Her hands were trembling as she searched through her purse.
The woman pushed her overflowing cart forward.
“If you’re too old to handle shopping, maybe stay home.”
People turned to look.
“Excuse me?” I said.
She rolled her eyes.
“I’m saying what everyone here is thinking.”
Mom touched my arm.
“Amani, don’t.”
