How do you feel about self-checkout now?

I went into CVS to get some post-holiday cheap chawklit. Two different ones near her now have two self-checkout lanes with an employee dedicated to standing there, doing pretty much nothing & no one at the registers. All of the candy was 50% off but not all of it was priced so I walked up to the counter as I wanted to know how much they were before adding to my bill when Mr. Do Nothing tells me I need to use the self checkout. I tell him I need a price check, when he tells me to come with him, about three aisles over is a price scanner where I have to scan the bar codes for prices.
I walk back with the couple of bags of candy I’m holding in one hand & scan the first one. He then tells me I must put it on the checkout shelf, which is so low it’s about 4" below my knees, about 1-1½’ below the scanner height. I walked the eff out, leaving everything right there. I refuse to shop where I must put stuff down on tables designed for little people; I’m not a freakin’ gorilla, my knuckles don’t drag; there’s absolutely no reason for me to bend over, repeatedly. Don’t tell me they’re so low because they’re designed for you to put your items in a paper bag (which you need to pay for). I had so few items I didn’t need to put them in any bag, a purchased paper bag or one that I did (not) bring with me.
I’m also not sure what the role of the employee was, standing behind people, not doing much at all. Oh well, the scale is happier that I left the candy there.
