I don't even use the machine!
I can buy pre-cooked sausage patties, pre-cooked egg patties, pre-cut cheese slices, and pre-cut muffins. I just toast and microwave as needed and I'm done.
I'll give you the cost breakdown later.
Most of the self checkouts have visual instructions. Sadly, a lot of customers don't follow them.
Those self checkouts have scales in the scanning area and the bagging area. And customers don't always put the items in the bagging area. That messes up the process. *groans*
I still use AIM for work. :)
I used it a lot when I was in college. I continued to use it after I graduated college... for a couple years. I stopped in 2009, except for relay calls on my smart phone. Started again last year for work.
