Local shop in ladies sandals

I decided to go to the local fish and chip shop at lunch time today (not normal busy)and plucked up the courage to wear some ladies sandals with a slight heel and male shorts. When i entered it was empty I was told it will be about 5 min's wait. While waiting ****ung ladies entered and waited behind me in the queue, I was now starting to get embarrassed. It then became aparent to me that they seen the shoes as there was a lot of smiles. The lady behind me tuned her back to me to say something to the others as if she was talking about me, It was then I realised they had seen the shoes. As I left there was a lot of giggles. Now do I do it again and maybe with a slightly bigger heel. I do wear ladies heels under trousers, but this was a first in shorts
