Barring other factors (e.g. PIN being mandated or a large number of customers demanding to pay with their phones), this is ultimately why it will take much longer than it has elsewhere for pay at the table to become common in the US (if it ever does). We're more likely to have optional pay at the front counter (mainly for mobile payments) than anything else.
