I catch the tram in to work at the moment. And this morning I didn't have any gold coins lying around so I thought it's about time I get rid of all my silver ones. I buy a zone 1 daily adult for $6.30. So I grabbed 63 x 10 cent pieces. got on the tram, waited for everyone else to grab their tickets cause I knew I was going to be there for a while. I select the ticket and started feeding the coins into the machine. I get to $2.80 left, and a message flashed up on the screen saying the machine is returning my coins. I thought WTF, here I go again. So i start feeding the coins into the machine again, a lot faster this time. I'm pretty sure it got to $2.80 again before it refunded the coins. Does anyone know if there's a time out on these devices? Or can they only accept 35 coins max or something? After the second failed attempt I decided not to bother buying a ticket. And there were no inspectors on the tram to verify this. I figure I have the money to buy the ticket. There's nothing on the machine to say that it will time out, or that it only accepts a certain number of coins. I'll try it again tomorrow. If the same thing occurs i'll get a free ride. If there are inspectors on the tram, can they really do anything? i have the money, but the machine wont accept it. I can't be at fault for that until they make me aware of what the problem is.
