If two guests are served the same amount of alcohol but one appears more intoxicated, what could be a reason for this?

A person with a lower body weight will typically have a higher blood alcohol concentration (BAC) compared to a heavier person consuming the same amount of alcohol, making them appear more intoxicated.

Frequent consumption of alcohol can lead to a higher tolerance, meaning that a habitual drinker might need to consume more alcohol to achieve the same level of intoxication as someone who drinks less regularly. Therefore, someone with a high tolerance may not show visible signs of intoxication as prominently. Hydration levels also impact how alcohol is absorbed and processed in the body. A person who is well-hydrated may metabolize alcohol more effectively, whereas someone who is dehydrated may feel the effects more intensely and quickly.
