The pizza configuration problem

Yesterday, at lunch, we had an interesting problem. Our group wanted to order a chicken pizza; however, we had one person who wanted red capsicum on the pizza, but no mushrooms; one other wanted mushrooms but no capsicum; and a few others wanted both. We ended up ordering a chicken pizza, half with capsicum and 3/4 with mushrooms; what we had in mind was something like this:

It took us a while to get the waitress to understand the order; we had to draw a diagram not unlike the one you see here. The fact that she was taking the order in a PDA-like handheld device can’t have helped. And we could see from our table that it took her quite a while to explain the order to the guy actually making the pizzas.

And it didn’t quite work out. In the pizza we actually got, the quarter that should have both mushrooms and capsicum had only mushrooms; so, it was a chicken pizza, 1/4 with capsicum and 3/4 with mushrooms. We’ll try again next week.

Does anyone know of a pizza place that will accept arbitrary areas for toppings and allow for the toppings to partially overlap? It’s probably not a common requirement, except maybe for places that frequently cater to geeks…
