    It’s always a good place to grab lunch after I get a haircut, I was greeted by a staff member by the name of Naidelin who always has decent recommendations when I don’t know what to order always patient I felt really welcomed and valued as a customer

    Has the size of the sandwiches changed or was it just this place? Whatever it is, I don't plan to come back here

    In their defense the county did give them an A rating. I don’t know how! The young lady that helped us was nice polite and worked as fast as she could. The older lady b was incredibly rude. The older lady checked us out and asked us what size drinks we wanted and we said whatever the standard size was for the meal, she said no you upgrade for 30 cents more. No we want what comes with the meal, she was visibly upset that didn’t upgrad. When went to pay the tap would not work. We wanted to slide the card because it always works that way and she said “No! You have to tap! We don’t do slide only tap!” Do my husband asked can’t I just insert the cup to read? Sharon as rice as can be “ NO TAP ONLY” the lady behind is said it OSS still broken, it was broke when I came over a month ago! We should have left and walked out. I paid cash but will not be back. And honestly I don’t know how they got an A rating their lettuce was so brown I would have rather them say we ran out of lettuce than use the brown wilted stuff. Also the spinach was so limp!!! The real reason I am doing a review and what is totally unacceptable is how rude the lady was.
