Goodbye after many years, have just seen my phone bill for sharing my booking via the app with 4 other people at £2.40 (65p per message!) and see other 15p charges for replying to confirm I will be attending at other bookings when receiving SMS from OpenTable.App deleted after many years of using and simply hadn't spotted. I suspect a lot of others don't realise. I'm sure it's in your small print of course conveniently hidden away and keeping you above the law.
