You don't actually need a smartphone, which is good because a lot of older people do not have them or can't use them.

I think people sometimes forget that you can inconvinience a waitress without being an asshole about it (they are there to provide service) and that being able to be a customer is important enough that most businesses would prefer staff spend time helping you.

Sure they would prefer you have a smartphone, and it may be less convinient but that doesn't mean they can't work to accomondate you.
