Bullshit, they're the know nothings who couldn't make it here who were too embarrased to demonstrate their ineptitude.
Which proves you have no business in a kitchen.
Why? They're expensive, very expensive for a true commercial machine (well over a grand), take up a lot of space, very heavy to move, and a bitch to clean... plus for anyone who is a klutz with a knife who can't slice bologna by hand it would be far too dangerous to be using a motorized meat slicer... many deli clerks are missing finger tips. But there are simple tricks for slicing deli at home; a sharp knife is essential, much safer/controlable than a dull knife... and for home slicing, fancy not being too important, first slice the hunk of bologna in half longitudinally, creating a flat for steadiness helps a lot plus slicing through less depth makes it far easier to control thickness... can do the same with a canned ham or roast beef, start by slicing in half to create a flat and shorten the slicing depth by half... who gives a ratz b-hind if you build a sandwich with half slices of salami... you'll not see or taste any difference... and eventually you'll gain skill so won't require the training wheels technique, you'll be able to slice full sized thin, even slices of even 8" diameter mortadela. Personally I have no use or need for a slicing machine at home, in fact I wouldn't want one for free... they are a BITCH to clean. Also, when one cooks a large roast beef for entertaining nine times out of ten the butcher at the store where you purchased it will have it machine sliced for free... always a good idea to introduce oneself to the store's meat department staff... custom ordering larger roasts than one typically finds in the display ensures better quality cuts, and not something that was cut and wrapped the day before. None of yoose douchebags need a slicing machine, yoose ALL need a decent sized electric meat grinder. Yesterday morning I bought a gorgeous ten pound top round roast, soon as I got home I sliced it into two 5 lb roasts, froze one and ground the other, great 12 oz burgers for dinner, on kaiser rolls... got four more 12 oz burgers in the freezer.
