Ours has the option, but what's the fucking point? So customers can look at you from an uncomfortable angle? Like, I'll make the connection at the window, byyyyeeeee. I'm literally never in front of the register anyways making drinks, grabbing from front, handing out cash, whatever the else I'm also expected to do while my drive is so long it's blocking traffic.

Ours has had it for years, we never use it.
