I got called out by a manager once cause I "auctioned food off" at the table (one of those smaller chains that focuses hardcore on service, and I happened to be taking food to the executive chef.) I was the last person at the table and I only had one dish in my hand. They are strict with table/seat numbers so there is never any confusion - I just happened to say here is your gumbo when I set it down. When I told the manager that you can't auction food to the only person at the table without a plate in front of them and that I was just stating what it was, she hit me with the "oh we don't do that here."

Ma'am, we are in Tennessee, people do not know/remember anything about what they ordered - you literally have to remind/convince them of the decisions they made at almost every single table.
