well....probably because he didn't tell them about the secret district 13...a place where they were thinking of a way to capture the capitol (and everyone hated the capitol in district 13) ...(catching fire and mockingjay)
they were also mad because they was just part of a plan and were being played by Haymith, the only one they trusted in the capitol...everyone else including some tributes (who were allies with Haymitch) knew about the plan
the plan was to stop and interfere with the quater quell and cause chaos before attacking the capitol! ...
later Haymitch told them he was keeping it a secret from just Peeta and Katniss because he was afraid they wont act or "play" it well and it wouldn't look real...he thought they might even get caught...
from the books catching fire and mockingjay!
he think they ratchet...
i think she feels like it was useless
In the popular book and film series, Haymitch Abernathyis the mentor of Katniss Everdeen and Peeta Mellark.Haymitch was their mentor in both the 74th and 75th Hunger Games. Haymitch was also the only living victor of District 12 before Katniss and Peeta, which is why they shared the same mentor.
haymitch tells them to act friendly, to act like a team.
Well Peeta loved Katniss for as long as he can remember so it was true when he announced his love for her in the interview but Haymitch said to Katniss that Peeta only said it to get more sponsors so it was Haymitch's idea to act like she was in love with him<3
Peeta knew that having romance in the Arena would give him and Katniss more supplies, more views in other words.
Haymitch is Katniss and Peeta's mentor. He trains them for the Hunger Games.
Sleep syrup, but this was in the book only. In the film, Katniss just got up and left when Peeta was sound asleep
Haymitch's second instruction for Peeta and Katniss are to find water.
Katniss, Peeta, Gale, and Haymitch
He's always drunk.
Stay Alive
To make Peeta seem like a tough competitor.
Marry Peeta. (This is a Catching Fire answer, not sure if what you were looking for.)
Because he knows that Peeta is innocent enough - the nightlock was not his plan - and that Peeta will charm and win over the crowd with his charisma anyway.
There was only one victor other than Haymitch, Peeta and Katniss. His name is not specified, and he was dead before the series began.
If they ran towards, they would be in the middle of the blood bath. Very few people make it out of the blood bath alive.
