Ping to a few pals.
I carry 2 wallets. Main wallet in 1 pocket and dummy wallet in 2nd pocket.
dummy wallet has those fake paper “Credit cards” that have some generic name, plus a dozen or so $1 bills.
It’s saved me from having to shoot idiots twice. The muggers always flee when they glance in it to see some green cash.
Think of all of the police interviews that I’ve avoided over the years, especially in foreign countries.
