I thought the correct way to do things in Macca's etc was to empty your tray of scraps in the bin and leave your tray on top of the box thingy.
The customers are clearly pigs, and the staff are either slack or there is not enough of them to run the whole show in a hygeinic matter.

I got food poising about 4 weeks ago from Mac Crap, Boy was I sick,,,,never again,

Yuk...Hangover food, I'm generally so sick I wouldn't notice................
