Hey waitperson, let me borrow your phone, I want to read the menu and order some food.
If they do loan, the next bump in the road is when it is time to pay, and you still do not use a personal communication device. Be sure that you do have some of that valueless paper money and conventual credit card to pay the bill.
No loan, time to leave, but speak to the manager before you relinquish the table for the next customer.
They will appear when it is obvious that you are there for the duration, if need be.
