My Grandma was still scarred from the Great Depression when I was growing up so always ingrained a bunch of weird rules into me. I still have money tucked in my shoe when I go out. She said to have a dollar bill in there at all times but with inflation I switched it to a 20. Can’t say I’ve had to leverage my “shoe money” since most places take cards but it has come in handy a few times across the past 30 years.
