That sounds like a dream self-service option.

in my experience it is:

1. Go put it all the things in the cart
2. Unpack each thing from the cart.
3. For each thing: scan it, weigh it, maybe you pack it in a bag. You get three bags, so no real option to organize, and hope you like plastic bags. Also zero table space to work with.
4. As you go, put the things you scanned on the cart with the stuff you have yet to scan, don’t mix anything up though!
5. if you scan too fast or encounter an item that is wrong in the system: get fucked wait a few min for an attendant to punch in their PIN so you can try again. If that doesn’t work, get fucked wait for a supervisor to come around and override whatever shit their system is doing wrong.
6. If you scan too slow or look at a prompt too long get fucked an attendant will be on your ass instantly to demand to know what you’re doing wrong. Yes this is contrary to the above wait time, and I don’t know why both of those things are true.

So yeah you can probably see why I hate self checkout.
