I don't make small talk with the wait staff. If they try to talk to me I answer with the least amount of words possible answers mostly consisting of: yes, no, and good.
I remeber when I was vacationing in Rochester last month. Myself and 5 friends went to a restaurant (Jack Ashtons or something like that) and the waitress came over (she was fairly good looking, maybe in her early to mid 20s ) and said "Hi, How is everyone" and we just stared at her. the she said "I said how is everyone again and I said "good" She took our drink orders, after I gave her mine and I went back to reading the menu. however the waitress was still talking to me. and said maybe 2 or 3 sentences. I don't know because I wasn't paying attention to her, but my friends were. I didn't figure out she was talking to me until my friend said "Rob, she's talking to you" but when I looked up I guess she didn't feel like talking anymore because my friends were saying "don't mind him".
and I din't think she was hitting on me becasue she was wearing a wedding ring.
