counterpoint: the place where I usually order my pizza (without an account, nice) has an optional field for phone number and they even write "in case something goes wrong". If this was an ecommerce order then yes, I'd rather be contacted by mail. If they have a new delivery person that can't find the building, I'd prefer to be called. But making it mandatory is also bad. What if I only had internet at a building but no phone number? Am I not allowed to order pizza?
