The answer is "on". wait on somebody/something 1. to serve food and drink to someone at their table, especially in a restaurant Ex: They have two people waiting on each table in this restaurant. 2. to wait for a particular event, piece of information etc, especially before doing something or making a decision. Ex: We’re waiting on the blood test results. 186 viewsSoოﾑ Яosｲﾑოɨ, edited 05:39
