I should say that one of ours isn't the friendliest place in the world. I was there one day trying to buy fabric and right in the middle of cutting my fabric one of the owner's inner circle of customers walked up, ask her a question and she walked away with the woman. After about 5 minutes I said, "Is she coming back?" The woman on the cash register said she'd go check. When the cash register woman came back she said, "She's on the phone now, something about her horses. She may be awhile." I left. Although I'm in a BOM there I buy very little else. I've also overheard her talking badly about customers to other customers which made me wonder what she says about me---very bad for business.
While I realize that as quilters we need them, as business owners they also need us. Business owners need to do everything possible to make their stores inviting. If I have a choice, I'm going to go where it's always inviting and cheerful.
