Self Checkout Lanes

[pokerdirty]

I frequently use these at the grocery store, because 1. I don't buy that much [censored] when i go to the grocery, and 2. It's fast and I don't have to wait in line (usually).

I don't find them particularly hard to use. You use the touch screen, you scan your item, you put it in the bag. Easy.

I find though, when i do have to wait for the next available lane, people take FOREVER to do this, and can't figure out how the machine works. If you are too stupid to figure out how to scan an item and put it in a bag, please, go play in traffic.

Does anyone else find this frustrating? Or am I the only one who uses these things so I don't get stuck behind the old jew at the grocery?
