As it has been the case on everything I've read from you, the main strength and the thing that just can't be beat in your stories is the damn PERSONALITY. Like, god damn it, these no good criminals had more charisma in this tiny fragmentary story than some villains in current movies : D and I love it!! The tension in the actual heist was great too! But I have to admit, I was more lost and deeply invested in the pre-heist banter.
What I have to say as a non-native english speaker is that the slang got a bit heavy to understand in some points @-@ But that is my problem really, not yours.
All and all, great and fun little adventure!!
