That works best. I walked in, found Keith and told him exactly what I wanted. He put me to the head of the line, instant BGC took about 4-5 minutes and I was out the door even though the store was packed. Know what you want first.Ditto on Keith's!
However, they are busy! Have what you want or want to know on the tip of your tongue! They won't fool around with you if your a time waster!
