How’s Your Wiener ?

Well here we go.
I was attending a Montreal / Boston game at the Montreal Forum (of course I didn’t pay for the tickets.) Years & years ago, btw
Between the second & third periods I was feeling peckish and decided to have a “Montréal Forum” steamier and a coke
I was standing behind what had to be an American ( or at least a non Montrealer) who ordered a hot dog all dressed, when he was presented with a hot dog with mustard and relish… he reminded the counter guy “hey…. I asked for this dog all dressed”
The guy with out blinking in a perfect Quebecois accent said ….
"MR, ear at da Form, dis is all dress !!,”
