I get a friendly hello when I go into my LQS. They always ask if I am looking for something special and are willing to assist me if that is the case.
Often times I am just looking with nothing in particular in mind. I like that they respect that and let me browse to my hearts content. They understand that I may leave without purchasing a thing, and that is okay with them. They know that the next time they see me I will probably spend $75 or more.
Only 1 of the four shops I patronize seems to be put out if I don't purchase something. I still will shop there because I like the owner..but her one salesclerk, not so much. This shop has a nice selection of batiks, so I have to go once in awhile. :D
