My most recent visit, has left me questioning the professionalism of this local establishment. During which, while Samara my cashier took my order, I observed two individuals in plain clothes walk behind the counter, passed her and three other employees, to what appeared to be the 1st drive thru window.

Whether or not they are current employees bears no bearing to individuals walking through the kitchen who have no pressing business to do so. In the professional environment, perception is huge and this perception is not positive at all.

After having gathered my food, and finished eating it, I observed a gentlemen place and pick up his order, walk towards the restrooms and turned around and placed his food on the counter to walk back to where the first two individuals went to. This lessened my experience that now three plain clothes individuals would casually walk behind the scenes (where my and other patron's food is prepared).

One star seems appropriate, but I'll give two assuming this was an isolated incident. Won't be going back for a while, though.
Output:
2 stars
