So, how familiar is this scenario:
You walk into a deparment store, hoping to browse through all their stuff, leisurely try out the various stuff they have on display, find that one thing that really gets your fancy, and walk out having made that perfect purchase.
But, what's this? Suddenly you find yourself hurrying just that little bit, suddenly you feel something boring into the back of your head. Suddenly you feel pressure.
And then you realise, there's a shop person on your tail. Trailing you every step you take. Literally.
Am sure there are some guidelines somewhere on the right etiquette for shop-persons. Tailing prospective customers within less than an arm's length is just not cricket.
