Setting up a junker character

[Potter Harry]

This isn't really related to the Junker Congress directly, rather a general help request, so a better section to post it would be here, in advance.

To answer your question, do you know how exactly a double bribe works? You aren't supposed to take the bribe the moment you find one. Instead, ensure the bartender is offering your Junker bribe, then switch inbetween the equipment dealer and the bar, checking every other NPC in the bar for one who offers a Junker bribe as well. There need to be 2 bribes present from 2 different NPCs at the same time in order to perform a double bribe.

If you've already done that, and simply can't find a second bribe, just keep trying. You might simply be unlucky.
