I always get followed, now either i look dodgy as hell, which personally i don't think i do. I have a great ass, theyre bored or maybe due to the nature of work we are simply more aware that we are being watched, and due to that very fact we quite possibly appear to act a little differently to joe average shopper so as maybe not to stand out. I don't know why really, i do know i must look the most guilty on the planet obviously.
And i can sympathise with the way you get looked at in shops for the way that you dress. I hate going into the higher class of shop as i do stand out like a sore thumb in jeans and sweatshirts and brasher walking boots. Do know of a guy who got drunk, slept in a ditch woke up and went into a car showroom and ordered a very expensive car whilst looking very much the worse for wear, when he went to collect the car it wasn't ready as they hadn't taken him seriously. The chap in general is an extremly wealthy guy and could afford ten such cars and not even blink about it...... Personally i'd have taken my business elsewhere. Comes down to the fact people are obsessed with appearances, and they seem to think those with the cash wander the streets attired in Gucci and Armani everyday of the week.
