You know, I can say at this point, and this is actually true, I remember like 30 years ago everybody just used Checkout because it was kind of convenient, you know, they would scan you and you have someone to talk to, you say, hi, how you doing, just sit there and shoot the breeze while they scan your items and it's pretty neat. Now you got yourself Checkout, it's like, what, and it's, that is so easy for people to still do, so it's really convenient for them.
