When you go into shops at the moment the sales assistants are on you like vultures.
Went into toyrus the other day and i was showing ds1 the bikes and ride-ons and this 'boy' was practically stuck to me like a magnet. Every time I moved he moved. I was about to tell him to back off but he started trying to sell me stuff.
Noticed it in other stores as well, and if you say you are just browsing they say 'what sort of thing are you looking for?' I think the trick is not to make eye contact, that seems to activate them.
