The bar on the bar

I remember when watching “Cheers” while growing up that the bar had two brass bars on it. Over the years, I’ve noticed them at several bars, but have never able to ask what purposed they served. So, what are they?

The bottom one is a foot rest, obviously. The top one is decorative - they’re a pain when you’re sitting at the bar, because they dig into your forearms.

OK, maybe it wasn’t “Cheers.” The way I’ve seen them are like C-shaped or right angled ones. Sometimes one, but I’ve seen two together They’re not across the bar lengthwise, but across its width.

I think those bars usually delineate the service bar, where the waitstaff will come to order and pick up drinks for the tables.

Yep. Not only does it denote the service bar, usually in a corner or at a less desirable place at the bar, but it is a place where it would be uncomfortable/impossible to sit or stand, which therefore makes a hole for the server during busy periods.

Those are also used so bartenders/bouncers can jump over the bar quickly to stop a fight. Or at least they were in a Bar bouncer competition I watched in the 80’s. Mr. T was the winner, IIRC.

I always figured it was a protective feature. It kept the edge of the wooden bar top from getting chaipped or broken by collisions.

I don’t know about jumping over a bar, but Stoli’s got it right IME. Depending upon the layout of the bar itself (both in front and behind the bar) this could be a convenient place for both the waitstaff to pick up drinks as well as for the bartender(s) to drop them off from either the tap location / well (aka rail) bottles shelf or the “top shelf” racks, if they are indeed on different sides of the bar.
