That's assuming they work, though. I can't tell you how many problems I have had at Friendly's because the waitress didn't close the check properly, or the machine was low on batteries or had a paper jam, or the Ziosks were at the wrong tables. The way other countries have the waiter carry around one machine seems a better idea, but then there is always an issue waiting for the machine, and since it seems to take longer to process than normal transactions, there is always a hold up.
