I've seen it happen a hundred times. I'm sure it was the old man's fault. Crotchety old goat. You may have seen this on the news about the man in Michigan who was hit by the Burger King employee and died. Read it here if you want but I'll fill in the blanks as to what actually happened.
--67 year old man walks in the front door of the BK: "Can I help you, sir?"
"It's too &^%$ cold out there!"
"Yes, sir. It is Michigan in the winter. What can I get for you?"
"It didn't used to be this cold when I was younger", he says as he ties up the line in front of several customers. "I remember the winter of '08. I was a teenager and was working on my Daddy's farm..."
"Do you need something to eat, sir?"
"Will this be for here or to go?"
"What did you say?"
Louder: "For here or to go, sir?"
His jaws finally close enough for him to utter, "Uhh..." and then stand there looking at the board over the employees head like it was written in pig latin.
"Do you have hamburgers?"
"What kind of burgers do you have?"
"Sir? Well...I mean...seriously? They are all on the menu. Do you need help with them?"
"Help? I don't need your help, punk! I was fighting in Viet Nam before you were a twinkle in your Daddy's eye, cheesebrain. "Help"! I didn't need your help when I was getting my elbows shot off in the DMZ in 69, did I? Why you little..."
Employee ducks and says, "Have it your way, old man!"
