You want and embarrasing moment.. I still want to fall through the floor!
I was at a nearby mall, just roaming around. There was a kiosk in the middle of the main floor with nothing but chocolate and nuts. I was standing there looking into the case of goodies when a young man came up and asked me if he could help me. My reply? "Not right now, I'm just looking at your nuts"! Everyone around me just started laughing and one guy even spit a mouthfull of his drink all over the place!
