Thank-you for making that point about staff pay, workshy - I was just coming back to comment on that, having read Carol Midgley's column in the Times this morning.
According to Carol, self scan theft costs hundreds of millions of pounds a year, and grazers (people who eat food on the way round the supermarket that they then don't pay for, because they dump the packaging, or because it can't be weighed once eaten) consume a whopping £2,7000,000 worth of food each year - and this cost is passed onto the staff (as well as in higher prices, because all supermarkets do include shrinkage in their price calculations) because they might not get a pay rise.
So, by shoplifting via the self-scan till, you could be helping make sure that poorly paid shop staff don't get a pay rise that they deserve and need. I would feel guilty about that - do you?
Carol also made the point that many small suppliers are paid according to the amount of their product that is sold, not the amount that is delivered - and stuff that is stolen will not be included in the amount sold - so the small supplier will have to bear that cost. You are literally taking money out of their pockets if you steal stuff provided by small suppliers. You could even be contributing to them going bust, meaning more and more goods on supermarket shelves will come from big business, which isn't entirely a good thing.
Yellowraincoat - I am sure it comforts you to assume that I am as dishonest or amoral as you, but I am afraid that I do do my best to live by my principles, and if I become aware that I have done something wrong, I do my best to rectify the situation - I apologise if I hurt someone, or I go back into the shop and pay for my sweets. And I have certainly never set out intentionally to steal from anywhere - and you can't say that, can you.
