Awkward situation

Have you had a situation where you felt that it was ok to take a picture of someone but in the middle of taking the picture the person yell at you with a loud voice no to take the picture?

We celebrated Halloween in our company and we always take pictures of every body who dress up with their different characters but there was this lady who was dressed up as a cowboy and I kindly asked her if I could take a picture of her but she refused as I was going to shoot her with a hand gun.  Later on in the party she was with other people taking pictures of her.

I really felt very bad.

I’d like to know what your reaction was and what did you do or say? Thanks.
