Every deli I've been to seems to be equipped with a slicer and a scale. Why hasn't anyone combined these two things yet? Instead of having the deli attendant slice some meat or cheese until they think it's about the weight you asked for, and then remove it for weighing, and then putting it back on the slicer to top it off (repeating as necessary), why not just build a scale onto the little platform where the slices drop down onto?
I am interested in any and all technologies which will (a) reduce the amount of time I must spend shopping, and (b) reduce the amount of time and effort between me and a sandwich.
(Does such a thing exist already? A quick Google search suggests not, but I don't know where to look for definitive information on modern deli supplies and equipment.)
