Another 'less cheap, more theft' tale.
I used to work in the operating rooms as a nurse. We weren't terribly well paid then, and there was often limited capacity to leave the OR block for meals, so most of us brought in something from home and put it in the communal fridge.
Frequently you'd come into the break room and find doctors, who were only there usually for a four hour session and all of them on much bigger salaries than the nurses, rummaging through our lunches for something to eat. Even though there were usually some forms of food (bread, cheese, tomatoes, cold meat, biscuits and sandwiches) provided for them.
Often on late shifts we'd bring in something to share - nice bakery bread, cake or slices. One night I brought in a large sweet iced bun, but I got stuck in a case until fairly late in the shift. Starving, I though 'Oh well, at least there'll be some bun!' No, not really. Some doc found it and scarfed the lot.
