Which behavior is a sign that a guest is experiencing impaired motor coordination?

Impaired motor coordination is a loss of the ability to coordinate movements. It can be caused by a number of factors, including alcohol intoxication, neurological disorders, and fatigue.
When someone is experiencing impaired motor coordination, they may have difficulty performing simple tasks such as walking, talking, and eating. They may also have difficulty maintaining their balance and may be more likely to spill drinks or drop things.
