Staff is inattentive and will make you come in and sometimes not even pay you for your time. UPDATE: As of 2/16/26 Staff is still awful and borderline confused if you ask then anything. Front desk is the worst. Made me check in and after AN HOUR AND A HALF she asked if I’ve screened yet. Completely incompetent you will more than likely just waste your whole day here due to the staff being so inconsiderate.
