Family in my case. There are two reasons they do this. A lot of people like medicine - they think it justifies the cost of the visit, and there's a real placebo effect (which is not an oxymoron as many might think).

The second is that many viral infections can, in rare scenarios, lead to bacterial infections. For instance a random flu can leave one more susceptible to developing pneumonia. Throwing antibiotics at everything is a defensive measure to help ward of malpractice lawsuits. Even if frivolous, it's something no doctor wants to deal with, but some absurd number - something like 1 in 15 per year, will.
