I agree too. It isnt the CUSTOMERS JOB to greet the shop owner or worker, for goodness sakes. The owner wants the customers money...they should make the customer feel welcome, and want to come back.
I waitress and bar tend, if I was grumpy and wouldnt talk to my customers, you think I would get many tips, or they would come back to me??? Nope. I help elderly, cut food up, greet you at the door, and SMILE!!!!!!! My LQSowner is the same way, always willing to help. I wish I had more money to buy stuff!
