I have another idea, Joanna in the middle of her shift is called by a costumer, an older lady who tells her that there is a guy sitting at another table who is acting strange and she thinks she saw him taking a picture of the backside of a beautiful lady who sat at the next table, Joanna had seen him before but never interacted, when he leaves Joanna asks several questions to Gena the restaurant receptionist who seems to know him, she tells her that his name is Luther and she plans to ask him out on his next day off, the next day Joanna decides to be the bait and check if it is true that he takes pictures, she notices signs which was enough for her to shrink Luther when he is alone, Joanna checks Luther's phone and sees that he has a whole gallery of not only her but also of her colleagues and much more, that angers her but at the same time she is happy that she hit the target, after spending some time with her "friend" she attends to a rich woman called Dahlia who had the perfect characteristics for Luther, big chest, and large thighs that squeezed her skirt, she orders a beef steak bathed with red wine sauce accompanied with mashed potatoes.

I have an idea you might like, a man name Anderson arrives at a restaurant and orders a dish and then complains that there is an insect in his food which is false because he was the one who put it there, but he makes it look very credible so that he receives compensation, causing the chef named Nicole to be questioned for not having noticed it, Joanna decides to give that man a taste of his own medicine and what better than to make Nicole be the one to eliminate the cause of her bad day, putting it in some egg tacos that Nicole eats on her break

The best chapter so far, and that way of describing with great detail is what I love the most, beside to knowing a little about Joanna's past.

Enjoying this so far! Keep it up! 

Here’s one idea (doesn’t have to be this particular story but in the same vain): a man at the restaurant is grossed out by a woman breastfeeding their baby and makes a huge scene to the point where the woman leaves feeling embarrassed and humiliated. Joanna gets revenge by shrinking the man down and then depositing him in one of her coworkers bottles used for their breast pump. The coworker uses the breast pump on their break and the man is soon trying to stay afloat in her breast milk. The coworker then goes home at the end of their shift, taking their pumped milk with them to give to their baby. 

Very good chapter, what if the next dish was a lasagna? And the client was a strict woman who works as an urban life planner
