A lot of my favourite bags, including Constance élans have been walk ins but I've never found it necessary to play games or buy things I don't want or need. Bag shopping is no different from any other shopping, I walk in, look around to see if what I am looking for is on display or just to see what they have that is nice, if not on display, when they ask if they can help me I tell them what I am looking for but not too specific, eg a nice Constance or nice Kelly or Birkin or whatever, or just a nice whatever colour I may be looking for. They always offer the nearest match to what I requested if they have it, or suggest something else. If they really have nothing I need I leave my number and don't waste my time or theirs touching things I know I won't buy. A smile and a friendly manner works wonders, some of my best pieces have been found just like that
