Personally, I really don't care if the staff rolls out the red carpet or bows before me when I enter a store or small shop. I prefer to browse without being bothered. If I need help, I know how to ask for assistance.
Sometimes I find it a bit annoying being followed and have someone behind me comment on every fabric I touch or show an interest in.
Dealing with textiles and such for all of my adult life. I do know a decent fabric when I see it.
I don't see what the fuss is all about. For me a simple Hello, how are you? at the register or cutting table is sufficient and a Thank you as I leave.
