Not bud, or buddy, or dude

Yesterday, because of proximity, I visited two stores that I usually attempt to avoid. When I go into a store, I would like to be greeted and helped (if I desire), quickly. This seldom happens at either of these retail establishments. But what really causes me to try to shop elsewhere is being addressed by any of the terms in the title, particularly by someone half my age. I am not their bud or buddy, nor am I a dude. I still think one should earn respect, but what I consider disrespect gains no customers. When I was in retail, I used the more southern custom of addressing people as sir or ma'am. This does not cover cases of what to call people considerably younger. Perhaps these are the times to use the vernacular popular and appropriate with the young people. But don't use it with me...
