This reminds me of what happened to my family on Friday night... our son is moving away he decided to invite us all out (group of about 10 family and friends) to one of those all you can eat sushi places where you order food on a pad and it gets delivered a few minutes later. My son God bless him snuck out about 3/4 of the way through dinner and decided that just so there was no confusion about who was paying, he had gone to the cashier and paid the entire bill. The rest of us were still sitting at the table when all of a sudden, our pad shut down. After flagging down one of the servers, he looked at the pad and his own digital device and said “you apparently are all done.... clear out because we need the table.” We were all looking at each other dumbfounded trying to figure this out when our son slipped back into his seat. Let’s just say that it required getting the manager over to our table and some choice words were spoken before food started to arrive again.....
