>good people pay x % extra because instead of bad people
Yes, and instead of making the stores more secure, or finding another solution, they just continue to let the "good" people solve their problems. They even introduced self checkouts in pretty much every supermarket chain now, to save more money.
I just don't care what is good or bad, I just don't like being ripped off.
So every now and then whenever there is a nice chance I will take something to get my x % back that were taken from me for compensation.
