Do you expect to be greeted at a restaurant?

Today I went to a burger joint and wanted to place an order, but for some reason the kid didn't want to greet me and kept looking down at his computer screen. Thought maybe he was busy placing another order so I didn't say anything. Then this girl who kept standing in front of the register who I already asked if she placed an order was like why don't you just say you want to place an order? I didn't say anything to her, but I mean I expect to be acknowledged when I walk up to the counter Is that too much to ask?
