Ordered pizza with half mushrooms and half peppero...

Ordered pizza with half mushrooms and half pepperoni. Get the bill and they charge for whole pie with mushrooms and pepperoni. Ask the waitress and get told "that's the way computer bills it." A good pie but next time it will be only plain.
Next time come in and see 2 empty tables. Host would not seat us because we were only 2 and he might need the big tables. Walked out for the last time. It's a shame as I've been going there a LONG time.
