Cloak Rooms - A Hidden Evil

To me a cloak room represents everything that is bad about society today. A place where you are often forced to store items - which you may desperately need - at a cost.
Take for example the cloak room at Acer Arena. First off, it is not explained clearly that bags must be cloaked before attending an event, then when you arrive you must queue for upwards of fifteen minutes with many other disgruntled, sweaty customers. The claim ticket then states that venue staff have no liability for lost or damaged goods. How is this fair? We haven't asked if we can store our belongings; you've forced us to, so take some responsibility. Pregnant women are even told to queue and store their bags - where's the common sense? What if I was to state, "I take no responsibility for lost or stolen claim tickets"? You wouldn't buy it.
At least this venue doesn't charge to store belongings, and chances are you'll get back what you left in one piece. But over at the Enmore Theatre, they pull the same trick but charge you for it, three dollars no less. With this slightly less professional storage system you feel less confident entrusting your possessions with staff. And again, no responsibility will be taken for lost, stolen, mutilated, eaten, regurgitated, sat on, express posted, entombed, boiled, cured or possessed possessions.
My question is, what's going on back there that you can't guarantee the safe return of my property?
