Where've your shoes gone?

Woman in charity shop: "Where've your shoes gone?"

Me: "I don't wear shoes"

W: puzzled look on face

M: "I've been wearing no shoes for 2 weeks for a project I'm doing, I'm a fine art student"

W: "What are you doing?"

M: "I'm testing the physical limits of my body so I've taken my shoes away"

W: "I'm going to call the woman upstairs and tell her about it. She might understand what you're doing"

I sheepishly walk away telling her "No please don't do that I don't want to talk to her" in the most polite way I can. Lady appears from a staff door just as I leave the shop. I hear the woman at counter start to explain my barefootness as I am walking away.
So bizarre!
