These days menus, tickets and even parking use QR codes. How do you feel about scanning a code for everything?

A natural way to answer

I think they are useful in many situations, like seeing a menu without waiting for a waiter. However, they can be a problem if your phone is slow or the signal is weak. So I have mixed feelings about them.
