IME, typical OC spray deployment would have a widespread effect with significant blowback for precisely the factors you mentioned, indoors and close proximity. If it was used in that situation, I believe several people including the drunk guy would potentially be affected. If you were able to hit someone with a direct stream to the face, they would suffer the worst of it if they were susceptible, burning and involuntary closing of the eyes, difficult breathing, etc. However, people in the close surrounding area would also experience coughing and breathing difficulties unless they moved outdoors pretty quickly.
