Self checkout has many advantages. First of all, in some
supermarkets, most people go to the normal checkout so self
checkout may be faster. It is also more "interactive" and fun to
do. Of course, if you have alot of items, it can be much faster to
go to a normal checkout. If you go to a normal checkout, the people
who work there would also scan your goods faster than you can. I
personally use selfcheckout except when i have alot of items.
