If someone had surgery on their ankle, is it ok to be around people who are drinking alcohol?

The post is a bit vague as to why one would think it might be a problem. Without some context that would change things I see no reason it would ever be a problem.

It depends. If the people get rowdy when drunk, avoid them. Alcohol is a poison that never did anybody any good, ever, so stay away from it. It will destroy your brain cells, facilitate development of cancer in many organs, including breast, cause hepatitis, cirrhosis and pancreatitis etc. There is no safe level of alcohol intake. Quit while you are ahead.
