Secure environment

In Europe, banks as well as bank customers suffer hard from scimming. Criminals apply small devices that can "record" the data on your ATM card when using the ATM. To save their reputation banks normally take full responsibility. However they ask customers to check the ATM and to make sure it's safe. That means we, the customers, are perhaps not blaimed but still made responsible for the bank safety.

So, why on earth, do banks let their ATMs look like this? And why isn't there never a sign with a phone number, that encourage people to call in when feeling suspicious?
