Sketchy looking place at a first glance and it is indeed sketchy. I have had money stolen from a cashier (Kalsi, a middle-aged woman with brown skin and is roughly 5' 5".) working at Zimmerman's twice in the past year. The first time, I let it slide. The second time, I contacted management (Martin Zimmerman) and he simply ignored me.
Just so that others do not get scammed the same way I do, I will describe how I had money stolen. I gave her a $20 and after she put the bill in the cash register, she claimed I only gave her $10. When I insisted otherwise, she got hostile and accused me of trying to take money. What she will tell you is that the manager will count the money and if there is surplus, she will contact you. An obvious workaround for her is to pocket $10 before the manager counts.
If you are paying with cash, I suggest you have the cashier identify the cash amount you are giving her. Have her verbally affirm that she sees the amount you are giving and better yet, record it with video.
