I work at McDonalds.
Only free food on our breaks and we're limited to spending '4 points' where certain menu items are worth 1 or 2 points each. Eg, Quarter pounder (1 point), fries (1 point) and a mocha frappe (2 points) or 5 chicken selects (2 points), apple pie (1 point) and a coke (1 point). Only menu item we're not allowed (from the top of my head) are 20 nug nugs and we are not allowed to have 2 main menu items (eg, a quarter pounder and bigmac or 5 selects and a quarter pounder - but you can have a 99p cheeseburger/chicken mayo/hamburger and a main menu item).
The only food I eat on shift is quality testing fries which is literally 1 slither every now and then. Although I have had a few frappes during my shift because they were made spare!
And yes, im sick of it so I make my own lunch.
