Review Cashier and Crew cannot follow through with a simple request

I ordered a whopper Jr meal just a few minutes ago at BK 2-EComm, MOA. I told the crew (as he was manning the cahier post) that I would like my burger with extra everything or 'heavy" . He acknowledged. Cashier comes in and I pay my bill and AGAIN mentioned I would like my burger with extra everything or "Heavy". My order was for take out. When I got back to the office and opened my meal, the burger was NOT EXTRA EVERYTHING and there was one small, pitiful slice of lettuce about 1 1/2 inches square. What's the matter with your people???!!!
