Final answer:
The claim that employees can consume liquor while working without patrons seeing is generally false; such behavior is often unprofessional and potentially illegal.
Step-by-step explanation:
The statement that licensees and employees can consume liquor while working, as long as it is not consumed in front of patrons, is generally false. Laws and regulations regarding alcohol consumption by employees on duty vary by region and establishment, but it is widely regarded as unprofessional and potentially illegal for employees to drink while working, especially in roles that involve the serving of alcohol. Consuming alcohol can impair judgment and performance, which is contrary to the responsibilities of maintaining a safe and professional environment for patrons.
