Do you have these where you live?
Self check-out counters at the supermarkets?
The customers scan the bar codes of the things they bought… and pay….
This is quite new here… I just think this is so amazing.
That is what trust is all about, don’t you think so too?
What about shop-lifters? Well, I guess that is where the conscience comes in… 
Besides, we think that the machines may be more economical in the long run compared to man power salary.
Whatever it is, I just think it is so cool… and convenient.
