I was checking a lady out at the counter and she was asking me if we had a piece of silver that was on one of our bracelets.... WHILE this lady was asking her question this other lady walked in and started talking right over top of her and asked me how much a certain piece was (even though the price was RIGHT in front of her face) I just said "I can help you with that just give me one moment to finish with this customer" and she SIGHED at me I was serving this other lady first.... and she was asking a question when this woman butted in and spoke right over top of her.
THAT is downright obnoxious. Some people just don't get it. Or plain just don't give a $^it!!!.
