I don't like the self-serve check-outs in the stores either. It seems nine out of ten times I have to call a clerk. If they want me to check out my own groceries I should get a discount!!
Many years ago when the airlines first got the self-service check-ins I hated them. Clerks would be standing at the counter not doing a thing and still wouldn't help you check-in. They'd just point to the kiosk. Funny, you'd think they'd want to help you, aren't the kiosk replacing jobs??? So with the airlines the kiosks were the beginning of a plethora of cost cutting methods. Then charge for meals, seats, luggage, etc. Will this be the trend with the cruise lines? I hope not!!
