Hit up Sonic today at lunch (yeah, I know, but I though I'd try the smash burger). Anyway, across from me, one of the spaces was blocked off with an orange cone. Pretty obvious to me it was because the intercom thing didn't work. So I watch in amusement as some woman sees the cone, and just kind of slowly pulls in and pushes it out of the way with her car. Then pushes the button on the intercom, waits, pushes it again, waits, all the while the carhops are walking by ignoring her. She finally waves one of the carhops over. I can't hear their conversation, but it looked pretty animated on her part. Carhop just kind of stood there and let her go off, said something, picked up the cone and showed it to her, and waited until she backed out and replaced the cone.
By that time the lunch rush had really hit, and I don't think there were any spots available.
edit to add: Smash burger was meh, like pretty much all sonic food, but their new fries are pretty good.
