Interestingly, Marks & Spencer don't have scales for your shopping (unlike all other self-checkouts). I wonder if there's cultural and demographic reasons for this. M&S is a very upmarket supermarket, so a potential thief (typically quite poor) is going to stand out like a sore thumb and end up with a security guard stuck to their waist. The larger supermarket chains (Tesco, Asda, Morrisons) have low-cost lines to cater for the wider market. That means it's harder to distinguish between a thief and a genuine customer, as they'll come from the same socioeconomic backgrounds i.e. they'll dress the same way. I wonder if there's crossover with what you see in the Netherlands?
