at corporate?
"You know, we're a high-end meats and textiles conglomerate, but the geniuses at corporate decided they wanted to diversify, so here I am." s01e21 "Milk", "How I Met Your Mother"
I couldn't find this usage of "corporate" in the dictionary.
Is it acceptable to you guys? Would you native speakers actually say it that way?
Or is this just the screenplay writer's experiment with language?
