W4n, careful there mate.
Especially that you are very new to this and you're (already) asking how to haggle. How would you feel if the very first words from her was "...So, is this your first time, honey?".
I would never ever haggle in front of a W/L, especially if she's caucasian. She will think negatively of a hundred things about you from just asking this question, especially if you are of a different ethnic background.
If it's your very first time in punting I'd take good long research on all the MPs and their prices. But do not haggle at all, period.
