Before deciding if a customer is intoxicated after observing signs, what other things might you do?

After observing signs of intoxication in a customer, it is important to also consider other factors before making a final determination. Simply referring them to a healthcare professional (option A) may not address the immediate situation at hand, and refusing service immediately (option B) may not be necessary if other factors are taken into consideration. While asking for a second opinion (option C) may be helpful, it may still not provide a complete understanding of the situation. Therefore, it is best to consider the customer's weight and other factors (option D) before making any decision. This allows for a more thorough assessment of the situation and may prevent any unnecessary actions.
