I don't see prisoners ordering pizzas as being one of their rights. Maybe as a reward for behaving themselves over a period of time. Not automatic.
To get a job in prison to buy pizza means they are behaving themselves and have proved they are worthy of employment while in prison.
On Sunday, everyone gets an ice cream as a treat. Is that too much too?
And one against those pampered hospital patients who prefer a horrible meal like pizza to that of the wonderful meals supplied by gov't contracted "caterers".
You'd be surpried what you get in hospital these days. If you want burgers, chicken fingers or pizza etc ask for the kids/teen menu and you'll get burgers, chicken fingers, pizza etc.
Same goes for airlines, when booking, book your food ahead and you get decent meals or you suffer with quiznos california wraps or veggies and dip like everyone else.
