I hate self-service checkout too. On 2 out of 3 times I use them, I have to get someone to help because I have got booze, aspirin, red bull, halls mentholyptus etc, or a DVD, or razors, or something with a plastic security tag on that they have to hoik off!
Or sometimes, there is just an 'unexpected item in the fecking bagging area!' OR I have bought something light and small (like a roll of dental floss,) and it weighs hardly anything, so the scale doesn't pick it up, OR I have an item without a barcode on it.
The list is endless.
At my local Asda, (a small-ish one,) they have twelves tills, and every single one is a bloody self checkout one. (Only the ciggie counter where you can get lottery tickets and top up your electric key, and buy bottles of spirits, has an actual person on it.)
In a BIG Asda 15 miles from me, they have 43 checkouts. Only SEVEN have people at them. 20 are self-checkout ones, and 16 are the 'scan-and-go' ones. .... Where you register your details with them, and scan stuff as you go along in the store, and then just pay at the end at the unmanned checkout. It's meant to speed up your shop - supposedly! Don't know if it does as I have never used it. Surely the same issues must come up, like when you buy booze or something with a plastic security tag on it!
I can't believe for a second that the public want this. Maybe 7 to 10 self-serve checkouts (out of say, 30 or 40, but not nearly ALL of them.)
I think it's a pisstake to accuse someone of being 'entitled' because they buy a load of stuff from a shop, and prefer someone to serve them at the checkout, rather than put it through a self-service checkout. WTF?! 
I mean, I use them sometimes, but I am not a fan of them. I think people are quite within their rights to voice the opinion that they don't like them, without rude and snarky comments!
