Get to Work Bug (Funny)

So.... My sim had a retail store called The Sweet shop. The price markup was 5% and she selled things from fish to flowers, but she didn't restock homemade things *EXCEPT HER BOOKS* and it was mostly run by herself. It was easy for customers to buy things, but a few minutes ago i was stocking the store with new things and decided to open it up. So, i opened it and no sims came. I did advertising, still no customers. But then i looked outside - there was a pool of customers sitting on the edge of the lot - They were dirty, peeing their pants, and their needs were probably very low, because all of them had that dirt you get on your sim when they have 0% hygiene. There were also mud puddles since it was summer and I had seasons. Has this ever happened to you? Well, i think its super weird! The customers eventually did come inside and buy from her, though!
