Short story but I got a good chuckle out of it.
A customer was spelling her company name out to me. Her company name starts with 'C'.
She said: "C like Kansas."
I mention I hadn't caught the first letter of her company name.
She says: "C like Kansas. C - a - n - s - a - s."
Me: "......Ok, got it. Thanks. C like cat."
Her: "Yes, or Kansas."
