"Nice trick with the fake wallet. Although I hear sometimes it enrages the muggers even more.
Do you carry it with you all the time?"
Yes, I carry it always and you're correct about them possibly getting angered by the lack of cash in it. I try to keep at least $15 in it but no more than $25 usually in five and one dollar bills. It's only meant as a distraction to get space between you and the bad guy giving you more time to get on target or better yet satisfy his need to have someone elses stuff. If he takes it and runs great, if he takes it and rifles through it in front of you his attention is on the wallet and not you.
