Waitrose in the UK is like that. They seem to place trust in the customer which feels nice. I don't know if they have some clever ways of monitoring customers, but it feels good not to be treated with suspicion. I've never had anyone check my bags.

Sainsburys annoys me every time. The slightest delay in putting the scanned item on the scale and it starts nagging you, very loudly. I avoid them as far as possible. M&S is the same - nice place to shop in, but self checkout is unpleasant.

The machines at one supermarket chains in Denmark are exactly the same as at Sainsbury's, even with the same woman's voice if you set it to English on the starting screen.

However, they are much less annoying here. I assume it's all just parameters that are tuned to local requirements.
