One of our city car parks, mainly serving the theatre, is pay on exit. A couple of weeks ago I fed my ticket into the pay machine and nothing happened. The screen display remained the same, 'Please insert your ticket', and the ticket remained inside. Panic. Hit cancel button. Nothing happened. My DD, equally concerned, noticed the 'Lost Ticket' button and pressed that before I could stop her. What she didn't realise is that if you lose your ticket you're charged the All Day rate. She thought it meant ticket lost in machine. The screen display said "Lost ticket, payment due £12". PANIC! I pressed the cancel button again, nothing. Again. Now the screen said "Weekly pass, payment due £50". HELP!!
Then, thank Heavens, I spotted the 'help' button, pressed that and within seconds I had a real person talking to me through a speaker on the front of the machine. It was all sorted then within seconds. Phew!
