I do not like the McDonald’s kiosk - I use it from time-to-time, as I did ordering chicken sandwiches last week (I’ve given up on Chik-fil-A long ago)
I STILL have to go to the counter to complete payment because I use the actual BOGO coupon from the previous receipt.
I DO love the BOGO deal on the receipt - takes about 1-1.5 minutes max to fill out with my phone.
Sometimes my order is so custom (Quarter Pounder with Cheese a special way) that I have to go to the counter anyway so I just skip the kiosk).
If the place is busy, I just go with the Big Mac (2 for the BOGO) as I don’t customize them, usually.
Same. Sometimes they offer free food with the phone app.
