Funny incident just now... I was getting Subway for dinner when I overheard the Subway staff asking the man behind me: "Sir, what sauce would you like?"
The guy said, "Mayo I don't want."
The staff heard mayo and faster than the man could stop him, squeezed mayo into his sandwich (there was a LONG queue and they were working really fast).
The man got very upset, "I told you clearly, mayo I don't want!"
Fortunately, he did not kick up too much fuss.
I mean... there are 8 sauces... you say "mayo I don't want", then... funny right?
