Payment for making a booking

I called 9th Avenue Waterside to make a booking and was told everything is done online and there is a deposit to be paid. I asked the lady on the phone what I must do if I do not have access to online booking, her answer was that only people with access to online are expected to go to their restaurant. Last week week I booked telephonically and a table was reserved! After supporting 9th Avenue Bistro for many years, we have decided to stop going there, the lady was impolite and not accommodating. What a pity!
