Christ knows where they find the burgers, but they certainly don't "make" them onsite. No it was ketchup-squirting for me, all day and every day. Actually it's a really difficult job, because the burgers come in trays holding twelve of them, and you have to remember exactly which ones not to squirt ketchup on. The "cook" shouts something like "hold ketchup on left side middle and bottom right corner" and that tray reaches you 10 minutes later, behind about 25 others, and you have to get it exactly right or a 4ft-tall Chinese lady comes along and screams at you. Look what you've done now, the nightmares are back.
