Self-Checkouts are great- I only have a few blahs about it.
Occationally, something in the system screws up so you actually have to WAIT for a warm bodied employee to come and FIX your problem (system will say "Please wait for assistance" or something similar)
The system will say "please remove item from bag" or something equally annoying EVEN if you scanned the item :P
And of course, there are people in front of you who are newbies that don't know how to work the self check out.
