Are self checkouts really 'failing' in other parts of the world? All the major supermarkets near me have self checkouts and almost everyone uses them. Unless you have a huge trolley full of shopping it's quicker and easier just to scan a few items, wave your card at it and you're done. I'm sure they get a bit of shrinkage but by and large everyone seems to do the right thing.

Now if only they'd remove that obnoxious "WOULD ya LIKE to PRINT a RECEIPT?" at the end... :P
