Really stressed and embarrassed after my dog had an accident in a shop..

I feel so upset and embarrassed after going in a dog freindly supermarket with my normally well behaved dog. She is 10 years and has never had an accident indoors before. Today she decided to poo in the middle of an aisle. I didn't have bags on me, so I had yo go up to the counter and explain the whole situation infant of so many customers. It was so humiliating, and I feel so upset and embarrassed.

The people thanked me for explaining the situation and being honest, but others were complaining about it. I feel so embarrassed, like I can't go in that shop again :(

I did some intense cleaning to try and reduce my stress, but I still can't stop playing it over and over in my head.
