What is surprising about haymitch's appearance when he comes to diner?

Haymitch's appearance at dinner is surprising because he is disheveled and unkempt, with messy hair and a generally unrefined demeanor that contrasts sharply with the polished environment of the Capitol. His lack of concern for his appearance highlights his disinterest in the superficial aspects of the Capitol lifestyle and underscores his struggles with alcohol. This portrayal sets him apart from other characters and emphasizes the darker realities of life in District 12.
