Dirtbags. I booked a table at a restaurant online and got a message via OpenTable asking to confirm the booking, I replied to the text with prompt "1" to confirm the reservation and I was charged for the pleasure of confirming the reservation, there was no mention in the text message that replying would incur a charge. You can reply "stop" to stop OpenTable messaging you in the future, but this also incurs a charge. Why any restaurant uses this platform is beyond me.
