Nearly caught in hardware store toilets

[Kingfisher28 272]

Called into my local hardware store for a few things. I had a look around at a few things and slowly made my way to the toilets. I went 1st into the men's and waited for a few mins before I tried the ladies. I opened the door to the ladies but God there was a awful smell in there, I didn't go in not just due to the smell but also heard someone coming! So I acted normal and headed out of area. The sales lady gave me a knowing look as she had heard the door bang shut but I pretended not to have notice.
