This is from a New York Craigslist post, from a restaurant owner who apparently viewed tapes of customers from 2004 and 2014, here is part of his account of the more recent behavior:
Customers walk in.
Customers get seated and is given menus, out of 45 customers 18 requested to be seated elsewhere.
Before even opening the menu they take their phones out, some are taking photos while others are simply doing something else on their phone (sorry we have no clue what they are doing and do not monitor customer WIFI activity).
7 out of the 45 customers had waiters come over right away, they showed them something on their phone and spent an average of 5 minutes of the waiter’s time. Given this is recent footage, we asked the waiters about this and they explained those customers had a problem connecting to the WIFI and demanded the waiters try to help them.
Finally the waiters are walking over to the table to see what the customers would like to order. The majority have not even opened the menu and ask the waiter to wait a bit.
Customer opens the menu, places their hands holding their phones on top of it and continue doing whatever on their phone.
