This one is telling on myself. Same gun shop I worked in I previously mentioned. Dumb HS kid. I called into NICS, and they proceeded to verify the information I had given them. Then as I'm writing down the info they gave back to me in phonetic alphabet... I'm writing down, and repeating under my breath as I write "chaarrrrlllieeee, liiiiimmmaaaa, fooxxxtrrottt..."
the NICS agent says "sir are you actually right down "charlie, lima, foxtrot...."?
"Yes ma'am"
"No! Charlie is for 'C'. Lima is for 'L'. Foxtrot is for 'F'"
I had this dumb look on my face and the other sales guy beside me is about to bust laughing, meanwhile customer is looking at me like I've got 3 eye balls.
