My horse got hurt a few weeks ago, and I realized of all of the first-aid items I had with his belongings, I hadn't grabbed extra leg wraps. (They were in another state with another horse.) I had one set of leg wraps, so he was good to go in his small paddock for the night, but with a forecast of steady rain, I knew he'd need a clean, dry set in the morning.

On the way home from the barn, I called Information and was put in touch with three farm- and horse-supply stores in the area. I knew they'd be closed when I called, but I wanted to know how early I could get there in the morning. Of the three stores I called, none had their retail hours on their answering machines. One didn't have an answering machine at all.

I've never done a formal poll, so I can't say this is the truth for sure, but if someone is calling your business after it's closed, they probably would like to know when you're open so they can, say, do business with you. Don't you think? Normal office hours of a service business are 8 - 5, so people would just know to call between those hours. But not every retail operation has similar business hours.

Putting your hours of operation on your website and your answering machine makes sense to me as a consumer. It probably makes sense to your other customers, too.
