Funny you say that because there IS one Chick-Fil-A location I know of that seems to be taking that exact route.
A few weeks ago they started doing indoor and outdoor repairs to this specific location and it turns out all they did was make the inside pick-up section smaller with a more open kitchen while making a THIRD drive-thru lane. I went inside there once to do an Uber Eats pickup and apparently the two women behind the counter told me that Uber Eats now has their own drive-thru lane for pickups. Keep in mind that in every other fast food place it's verboten to even use the drive-thru for that sort of thing, so idk why they decided to do it for this Chick-Fil-A in particular. All I know is that the way the two women were describing it to me was like they were pissed off I even came inside in the first place, specifically the tone they used when one of them said "we'll give you the order here inside THIS time, but now you can use the drive-thru". Like bitch why the fuck does it matter? I'm already here, just give me the fucking order.
