As common as this is it doesn’t make sense. When we use letters to represent words in an acronym such as ATM we really are using a shorthand method of saying “Automatic Teller Machine”. Also the acronym PIN means “Personal Identification Number”.
That means a person who said, “I’m going to the ATM machine but I forgot my PIN number.” really is saying “I’m going to the automatic teller machine machine but I forgot my personal identification number number.”
Why would a person want to say “machine machine” or “number number”? It's another one of life’s mysteries I probably won’t live long enough to figure out. Oh well, I really don’t care care. It doesn’t make any difference to me me.
