ways to ride grouse for free:
since all their employees are retarded, you can easily sneak past the side gates without the ticket scanner retards seeing you. You will see the side gates, just time it right. You can also borrow a friend's pass and wait till the very last person has been scanned, then walk through the gates; when the retard scanner asks what you are doing, say you forgot your gloves on the stairs or something, and had to go back and get them, then if they scan your pass gain and it does the double beep (which means that they scanned it recently) you have an excuse.
You can also recycle comp day tickets and use them as many times as you want, as long as there is no date on it, it will keep working, and if if does the double beep, claim ignorance and you'll get through fine. The retard scanners are usually so busy at the bottom, that they dont have time to be hassled, so any little inconvenience you throw at them, they'll just let you go, as they need to keep on schedule with the tram.
