Paparazzi continuously bake cakes when at a celebrity sims' small business

My sim is a max celebrity and gets swarmed by paparazzi, but whenever they are running their small business despite having the fridge and oven in an employee only area, the paparazzi will go over and bake cakes which they then leave around. This is a hassle. 

Annoyingly it then makes Sims complain about the store being dirty.

The only activities at the business is to buy items and be friendly.
