I have decided to stop shopping at my local Marks & Spencer store due to the intimidating security staff following me everytime I am shopping there. I have no idea what I am doing to attract their attention but clearly they have singled me out as a potential shop lifter, I find their behaviour very intimidating. This is not an experience I have had at any other supermarket. I know some of you will say but if you are not stealing anything why let it bother you, these security men are blatant in the way they watch you to the point that other shoppers notice. Maybe its because I take my own carrier bags which is what M & S have encouraged us to do,whatever the reason for being followed everytime I've had enough and won't be giving M & S my business anymore, AIBU?
